 Which of the following threats to internal validity can apply even when a control group is used? Free Multiple Choice Observer bias can threaten which of the following big validities? Free Multiple Choice Which of the following is NOT a method researchers used to identify or correct for attrition? Free Multiple Choice Dr. LaGuardia is curious as to whether children in a daycare center will share more after watching an educational video on sharing. Immediately before and after the video, he has several undergraduate research assistants code the sharing behavior of a group of 33 four-year-olds. Which of the following would you recommend to him to decrease the threat of instrumentation? Multiple Choice In previous studies, Dr. Schulenberg has established that finding meaning in one's everyday work activities can lead to greater success in the workplace (e.g., productivity, creativity). He is curious as to whether this can happen in the college classroom. Specifically, he is curious whether finding meaning in one's classroom experience can lead to greater academic performance. In the spring semester, he has his teaching assistant randomly assign half the class to write a paragraph each class period about how the material has meaning for their lives (meaning group). The other half writes a paragraph about what they did to prepare for class (preparation group). He does not know which of his students are writing which paragraph, and the students are not aware they are responding to different writing assignments. To measure academic performance, he gives the students a midterm essay exam and a final exam. Imagine that in Dr. Schulenberg's study, he notes that all of the students do extremely well on the midterm exam. When he looks at the results of the final exam, he notices that all the students' exam scores went down. Which of the following pattern of results would suggest that there is a threat to internal validity? Multiple Choice Regression is especially problematic in which of the following situations? Multiple Choice When interrogating experiments, on which of the big validities should a person focus?

Multiple Choice Which of the following can help prevent testing effects? Multiple Choice Which of the following cannot be found in a one-group, pretest/posttest design? Multiple Choice Which of the following studies would NOT have a possible threat of observer bias? Multiple Choice Dr. Whetstone is curious about how self-esteem changes as a result of a new counseling program. She is concerned about testing threats in her study. Which of the following would you recommend to her as a way to address this type of threat?

Multiple Choice Which of the following is not one of the three most common threats to internal validity?Which of the following is NOT one of the three most common threats to internal validity? Floor effects are a special case of weak manipulations and insensitive measures, not one of the three most common threats.
Which of the following is a common and effective solution to threats to internal validity?Altering the experimental design can counter several threats to internal validity in single-group studies. Adding a comparable control group counters all threats to single-group studies. If comparable control and treatment groups each face the same threats, the outcomes of the study won't be affected by them.
Which of the following is a reason one might choose to use a double blind design?A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.
Does observer bias threaten construct validity?Observer bias can affect internal and construct validity Using a double blind study can prevent demand characteristics and observer bias. When a double blind study is not possible: A masked design may be possible.
