SimUText Quiz Latest Update Graded A Why should you friend NOT attribute the difference in test scores to study music? a. the study environments of your two friends may have differed in other ways that could impact test performance b. your friends differ in other ways, such as their prior knowledge of the subject and their level of test anxiety c. a difference between only two people doesn't demonstrate a clear pattern d. performance on only one test doesn't demonstrate a clear pattern a, b, c, d Suppose you decide to design an experiment to test your friend's hypothesis about classical music and studying. How will you define your variables? a. both study music and test performance are potentially confounding variables b. independent variable: study music, confounding variable: test performance c. independent variable: study music, dependent variable: test performance d. independent variable: test performance, dependent variable: study music c In the experiment you're designing, what would you call the group of people that listen to classical music while studying? a. control group b. experimental group b Which of the following could help improve the scope of inference for your results? a. conducting the experiment multiple times during the semester, and not just a single week b. assigning sections to be in either the experimental or control group based on how easygoing the TA is for each section c. increasing replication by having 5 sections in the experimental group and 1 in the control group a Suppose you want to set up an experiment to test the hypothesis that electromagnetic fields cause CCD, and you have 6 bee hives to work with. Which of these is the best experimental setup? a. 6 hives exposed to high levels of EMF b. 5 hives exposed to high levels and 1 hive with no EMF exposure c. 3 hives exposed to high levels and 3 hives with no EMF exposure d. 2 hives exposed to low levels, 2 hives exposed to medium levels, and 2 hives to high EMF levels c Suppose you find that the colony collapse rate is slightly higher among bee hives exposed to EMF than among hives with no exposure. What can you conclude about the hypothesis? a. exposure to EMF may or may not cause or contribute to CCD b. exposure to EMF definitely causes or contributes to CCD c. CCD is more likely to be caused by pathogens or pesticides a A good experiment must include: a. groups that differ only in hypothesized casual factor(s) b. at least one group that includes a potentially confounding factor c. at least one group that differs from the control in multiple ways d. groups that allow for many comparisons, including those not directly related to the hypothesis a Some researchers have hypothesized that reading fiction can increase empathy in children. What prediction follows from this hypothesis? a. students who have high empathy scores on psychological tests are more likely to read fiction b. students who read fiction are more likely to have high empathy scores on psychological tests c. all students who read fiction have high empathy scores on psychological tests d. students who don't read fiction don't have high empathy scores on psychological tests b Suppose your friends decide to test the hypothesis that reading fiction can increase empathy in children. They randomly choose 2 kids from a local school. They child 1 child a nonfiction book to read and the other child a fiction book to read in the same amount of time. Before and after they have read their books, your friends give each child a standard psychology test for empathy. Which of the following changes would make your friends' experiment better, and why? a. include more children in the study b. include more books in the study c. select children that are the same age and have the same teachers and classes a, b, c
