The first premise states that the theory, or the explanation, really does enable you to predict the facts, or the observable outcome. A frequently observed and poorly understood phenomenon in which there is a positive response to treatment with an inactive substance. Statistics are used by scientists mainly to determine: Whether differences in results between control and treatment groups is significant and important. He decided to study the environmental impact of this herbicide on blue jay reproduction. An even subtler example can be found in academic discussions of the theory that punishment motivates learning better than does reward. B. Youll seethe audience will applaud at the end. If it is a singular explanation, you can ask if it is the sort of thing that is known to happen, and if it tends to happen more frequently than do the alternatives. Note: See Section 6. The second premise states that the observable outcome is known to have happenedthat it has been observed. WebSchedule 1 - Dictionary . Complete each Both explanations do an equally good job of entailing Periers results as their observable outcome. Select the correctly ordered list of psychological theorists, with the earliest theorist listed first. No one would have expected a comet in December 1758 unless they were assuming the Newtonian explanation; such an event would have been extremely improbable. An explanatory hypothesis is a type of hypothesis which is used to test the cause and effect relationship between two or more than two variables. It will be proven when I get some sort of raise in the next few years. Which of the following is NOT a useful step in resolving peer conflict (especially in teenagers) in a nonviolent way? An inactive substance used in controlled experiments to test the effectiveness of another substance; the treatment group receives the substance being tested, and the control group receives the placebo. Neither of the two alternatives has been ruled out, and either is more probable than that she is one of the very few people who has perfected special coin-tossing skill. Simplicity contributes to epistemic probability, so ask whether the explanation is sufficiently simple. d. a and b b. frustration-aggression theory WebA hypothesis is a potential answer to the question, one that can somehow be tested. Senator Claiborne Pell (D-RI), wrote an alarmed letter to the secretary of defense; he had discovered the word simone (pronounced si-MO-nee) in the secretarys taped speeches, as well as in the speeches of the secretary of state and of the presidentwhen the speeches were played backwards. Part Four: Evaluating the Truth of the Premises. her own conscious experience. Dr. Sarkeesian observes and records how watching cartoons influences heart rates. The set of analytical and mathematical tools designed to help researchers gain understanding from the data they gather is called. A set of analytical and mathematical tools designed to further the understanding of numerical data. b. e. superintendents, c. students with good leadership and communication skills, Which of the following is NOT an aspect of the revised frustration-aggression hypothesis? Organisms can grow and develop, and they carry information relating to these and other processes that they can pass on to offspring. Sample exercise. It is just an explanation, designed to make the unexpected experience easier to understand. Dont worry about whether the outcome has much likelihood of being true (since that has to do with the truth of premise 2, not with the logic of the argument). In some cases, it can be tempting to accept an explanation with an extremely low prior probability simply because you cannot think of any plausible alternative. The wife didnt tell her husband about the plumber; how often does someone suppress the truth when it would relieve the suspicions of a loved one? a. A statement that enables us both to predict and to better understand the cause of that which it explains. We typically favor the explanations with the highest prior probability. The plumber says he went to a house, while the man says he lives in an apartment; how often does someone make that sort of mistake? The other roots the power of suggestion in physiology: extreme fright and despair disrupt the sympathetic nervous system and paralyze body functions. d. Aggression facilitates performance only in team-sport athletes. They took me off all of them and since then Ive had no attacks. In another example, continental drift initially was reasonably rejected as the explanation for the striking biological and geological similarities between continents that are widely separated by oceans because there was no known mechanism for the drift. Falsifiability applies when there is some possible observable outcome of the theory that could prove the explanation to be false. Many would argue that both the theory of evolution and creationism are equally probable because, after all, they are both theories. a. situational causes Ideally, the explanation contains a cohesive and cogent understanding of the origins of the problems, the conditions that perpetuate them, the obstacles interfering with their solution, and the resources available to address them. Then-clause is said to be unlikely without if-clause. As the decades passed it was not forgotten, and the comet appeared on Christmas Day, 1758. In the 17th century, the Italian mathematician Torricelli hypothesized that the Earth was surrounded by a sea of air, which decreased in pressure uniformly as the altitude increased. . c. Small-scale, on-the-field aggressive acts serve as triggers for crowd aggression. a. A second way of distinguishing among explanatory arguments is in their level of generality. It is conducted to have a better understanding of the existing problem, but will not provide conclusive results. A. a. To illustrate how this strategy is related to the prior epistemic probability of the outcome, suppose I propose the following fanciful explanation: I am bewitched, so that gravity has no affect on me whatsoever; the only reason I am able to walk around on the ground is because of magical shoes that counteract the bewitchment when I wear them. These youngsters had, in fact, been selected at random from among their classmates. Falsifiabilitythe requirement that it be possible to specify some observable outcome of an explanation that could prove it to be false. That smacked of the sea. Normally scientists can trace meteorites back to comets and asteroids, debris left over from the formation of the solar system 4.6 billion years ago. All of these. First, its conclusionthat we are above sea levelis an explanation. WebA hypothesis is a potential answer to the question, one that can somehow be tested. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Sample exercise. The observable outcome follows from this explanation just as well as it does from the explanation that it was merely the butler who did it, but the simpler butler explanation has a higher prior probability. Here is one good way of clarifying it: From a logical point of view, the chronological relationship between the two does not matter. But when, having slept in the car, your friend says, This water boiled quickly, so we must be well above sea level, this is offered as a reason to believe that we are well above sea level. She is a great actress. Muluple Choice Young women purchase fewer meats than women who are 35 years of age or older. Which of the following statements is CORRECT? Step 2. Influenced by the confirmation bias, you proposed a number that would confirm your preferred answer. C. An increase in family income leads to an increase in the percentage of income spent on housing. There was no control group with which to compare his patients who received the treatment. He said he came home to discover a well-used pipe in the pocket of his bathrobe. Sales of vegetarian foods vary by season. How to Think about High Enough Prior Probability of Explanation. Clearly an army doctor, then. Explanatory/ Causal /Bivariate Hypothesis. There are two types of hypothesis. c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power. . The International Society of Sport Psychology developed a position paper on aggression in sport. But Grayson believes its unlikely such factors fully explain the statistics. An experimental design in which the subjects do not know what treatment (if any) they are receiving. b. Sales of vegetarian foods vary by season. Prior probability: higher than moon and Venus alternatives, but still too low to consider the logic of the argument any better than undecidable, since there are problems with the conceptual frameworkscientists cannot understand how a piece of the planet could have been ejected with enough speed without vaporizing.. But you would have done far better to propose, Seven is not in the set. If you had been right, you not only would have confirmed your preferred even-numbers answer, but also you would have ruled out the whole-numbers alternativethereby improving the logical support for your answer. Also termed the data, the prediction, or the facts. Woman on a TV talk show with theme Moms who keep secrets from daughters: Mom, you always told me that my father was killed in the war right after I was born. If Newtons account of celestial mechanics is correct and applies to the motion of comets, then a comet with an orbit similar to the 1530 and 1606 comets will appear in December 1758. b. Signs that an Argument Is Explanatory Rather than Fallacy of Affirming the Consequent. D. It excludes the presumption of causation. Sample answer. d. as an inverted-U Clarify the explanatory argument in each of the following passages. Write a paragraph about the 1760 s in the American colonies in which you use these vocabulary words: Why did Austria-Hungary object to Serbia's desire to establish an independent state? a. assertive behavior. Psychoanalytic theory focuses on ________ and early childhood experiences. You must have observed the way in which he held his head and swung his cane. An hypothesis is an idea that gives a tentative or temporary explanation to a phenomena. The experimental subjects do not know which (if any) treatment they are receiving. In the case study of Billy the hockey goalie, what did he learn? Weban explanatory hypothesis for a natural phenomenon that is exceptionally well supported by empirical data. Suppose I have heard that vitamin C prevents colds; I dont know whether to believe it but decide its worth looking into. Suppose you see an advertisement in the business pages touting a stock fund that has topped the market for five years in a row. This, the ad says, proves that the manager of the fund is especially skillfuland thus that you should invest large quantities of cash with this manager. The achievement is all the more remarkable when you consider that the mysterious sculptors created their masterpiece millennia before the existence of their subject. 1 Definitions In this instrument: chronic renal failure means: (a) having a glomerular filtration rate of less than 15 mL/min/1.73 m 2 for a period of at least 3 months; or (b) a need for renal replacement therapy (dialysis or transplantation) for treatment of complications of decreased glomerular filtration rate A deductive process based on testable and measurable events. A useful scientific hypothesis is one that is: A hypothesis that states that there is a lack of relationship between two factors is called: When conducting a scientific experiment, which of the following is tested? In a short paragraph, identify the explanation, discuss why it may be unfalsifiable, and explain how this results in a problem with the first part of the total evidence condition. The first part of the total evidence condition is that the observable outcome must have a low prior epistemic probability. Conduct the experiment over and over again. What is meant by the phrase "hierarchical organization of life"? The leading alternative explanation is that the manager has succeeded by sheer luck. And the argument concludes that the explanation is thus true. Hundreds of people gathered for a second night Wednesday to see an image described as the outline of the Virgin Mary on a wall of an empty house in Hanover Township, Pa. Reject explanatory arguments that have unfalsifiable explanations; they are in principle unable to satisfy the first part of the total evidence condition. For singular explanations, ask whether this sort of explanation is known to occur and, if so, if it occurs more frequently than do the leading alternative explanations. , For years, scientifically trained observers dismissed voodoo death as primitive superstition. The simplicity test, as explained here, is related to the makes-sense test. Frustration increases the likelihood of aggression. For a scientific explanation to be testable, it must also be ________. For general explanations, a good way to check for simplicity is to ask whether the explanation predicts the smoothest possible curve.In the 17th century, the Italian mathematician Torricelli hypothesized that the Earth was surrounded by a sea of air, which decreased in pressure uniformly as the altitude increased. a. assertive behavior. Theories are hypotheses that have been proved. . To put it more generally, to say that an explanation or an outcome is unfalsifiable is to say that any observation at all is consistent with the explanation. [5] A graph of these results, representing our evidence in this case, looks like this. Please give like. How often do plumbers waste time by doing things such as drying their clothes when they can make more money by going on to another job? This result can be explained by the fact that because the teachers expected them to do well, their perceptions of each students ability rose and those childrens own self-image was enhanced. David Lewis and James Greene, Thinking Better. WebA hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. The requirement that it be possible to specify some observable outcome of an explanation that could prove it to be false. . This is a dirty trick. Want to create or adapt books like this? Abbys explanation is that the wife is having an affair; the observable outcome is that the pipe unexpectedly appears and then mysteriously disappears. If you are like most people you suggest, Eight is in the set. And my reply is that yes, 8 is included, because I am thinking of the set of all whole numbers. It describes why the individual is having problems. Statistics and Probability questions and answers, Which of the following is an explanatory hypothesis? Pa! exclaimed the youngster, they are getting ready to pee on the hay! Well, son, replied the father, youve got the facts all right, but have reached the wrong conclusion. Lincolns client, we are told, was acquitted. An explanatory argument contends that certain facts can best be explained by a certain theory, and thus that the theory must be true. c. psychologically harming another individual C. An increase in family income leads to an increase in the percentage of income spent on housing. If higher expectations by teachers and by themselves causes students to perform better, then randomly selected students whom teachers believefalselyto have greater potential end up performing better. Record the facts. Another contemporary of his, French mathematician and philosopher Blaise Pascal, suspected that Torricelli was right but that a greater altitude was required to prove it. In some explanatory arguments, the explanatory theory is first invented, then the observable outcome is predicted and looked for. Delayed on the way west in 1846, 87 pioneers were stranded in late October by heavy snows in the Sierra. It is much harder to invent an explanation that successfully predicts future observations. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. General explanationsNewtonian celestial mechanics, for exampleare intended to apply broadly; Newtons theories explain the motion of all heavenly bodies at all times. After a few seconds, I knew it was. Barbecues occur far more frequently than house fires, so they have a much higher prior probability; but when the observable outcomeway too much smokedoes not follow from the barbecue explanation, we are logically forced to the less probable explanation that it is a house fire. Just like the coin-toss and mutual fund cases, coincidence does make sense and is at least as likely here as the paranormal. This observable outcome easily follows from the Newtonian explanationthus, it would provide us with an argument with true premises. a. fans become less aggressive after watching a sporting event Organisms are able to maintain relatively constant internal conditions that may differ from the external environment. But you can still ask whether such explanations make sense, and whether they make more sense than the alternative explanations. Which of the following have shown the strongest relationship? And, finally, you can ask if the explanation is sufficiently simple. Personal Finance Semester 1 Test - Mrs. Ellio, John Lund, Paul S. Vickery, P.

Henretta, Rebecca Edwards, Robert O. Self. A Guide to Good Reasoning: Cultivating Intellectual Virtues, Creative Commons Attribution-NonCommercial 4.0 International License, The Total Evidence Condition (1): the Improbability of the Outcome, The Total Evidence Condition (2): the Probability of the Explanation, [If we are well above sea level, then water boils quickly.]. Why? The argument might now be clarified as follows: Given that the explanation calls for a uniform decrease in air pressure, it would then predict that if samples were taken at all other altitudes on the Puy-de-Dome, they would be plotted on the graph along a line described by the smoothest curve that can be drawn through the points already there, as follows. It is an argument. Being a plumber, I was summoned to the home of an attractive woman to repair a faulty shower nozzle that was spraying water all over her bathroom. A. Note: See Section 6. Rather, it is simply necessary that it not be implausibly low and that it be higher than that of the leading alternative explanations. b. thought out versus impulsive c. Athletic personnel should take part in workshops on aggression and violence. d. a and b. e. a and c. b. in the quest of some nonaggressive goal. His argument would gain some logical strength if, when we looked for them, we could find sexual images in advertisements more often than we find them in the clouds. It always does reappear after an eclipse when much noise occurs. This is the place to ask about coincidence as an alternative explanation. But the second letter, using the same observable outcome, offers an alternative explanationnamely, that a plumber visited, left the pipe, then surreptitiously retrieved it. b. The logic of the gods argument would benefit if its observable outcome ruled out the luck alternativeif, for example, the outcome were revised, as Bacon hints, to this: Nobody who worships the gods has drowned in a shipwreck. B. All of these. After one of our couple friends started going to a fertility clinic, they just relaxed and stopped consciously trying to conceive. But the first one, Torricellis, has a higher prior probability because it is simpler, due to its prediction of a smoother curve. Another explanation for the sunrise already exists in our own background evidencethat the earth is rotating on its axis. Neither the researchers nor the study's participants know who is receiving the drug and who is receiving the placebo. Hypotheses and theories not supported by trustworthy and methodical scientific studies. d. And what is the prior probability of the skill explanation? So the logic of the burglar argument is shown to be weak. Is the foundation of all scientific experiments.
