Match the internal validity threat to the proper example.Here are the complete statements for the answer options: Participants take a pre-test in the beginning of the semester and a post-test at the end of the semester and exhibit the practice effect. Participants begin to drop out of the experiment when summer begins. Experimenters select test-takers who scored at the lowest percentile to teach them test-taking strategies. Participants begin to fall asleep during the experiment. Participants in the experimental dance class begin to show the control group dance moves they've learned. Experimenters choose students enrolled in online classes and other students enrolled in face-to-face classes.

Identify which one of the four types of validity: measurement validity, statistical conclusion validity, internal validity, or external validity—is it violated in each of the following scenarios? Explain your decision. After a successful Phase 3 clinical trial in which their new drug improved symptoms in children with asthma, the pharmaceutical company announced in a press release that it had developed an asthma drug that the whole family can use. As a test of intelligence, researchers administered a 40-question American history test to the study participants. The average score was 15 correct out of 40, thus researchers concluded that study participants are not very intelligent.

Text: Match each example to the type of validity it illustrates. Match the example with the validity on the right side of the table. Write the answer. Example Type of Validity If this exam measures your mastery of the material presented in the first month of this course, then it can be said that this exam is a good measure of A. External validity If your NEO-PI results match very closely to another personality test you took online, then it can be said that the online test has high B. Content validity If a student with high SAT scores also has a high GPA, it can be said that the SAT has high C. Predictive validity If the results of a research study conducted only with college students can be generalized to non-students, it can be said that it has D. External validity When the researcher has controlled for demographic variables so that the research question is influenced by the independent variable being studied, this study can be said to have high E. Internal validity
