#1 Someone is taking a psychological assessment for the second time. The first time they took the assessment, they simply guess at the answers. The second time, they remember how they answered before, and answer the same way in order to be consistent. The test will probably be ⁃ The correct answer is reliable but not valid. This is the right answer because the test is reliable but the validity of the test is compromised because it is not actually measuring what we want it to measure because the participant is not answering in an honest way but is just remembering the answer they put the last time they guessed on the test. #6 Evidence of good construct validity would be present in a multitrait-multimethod matrix if - The correct answer is you have stronger correlation scores between measures of the same construct (trait) than between those using the same methodology. This answer is true because it shows that the instruments used for measuring is accurately capturing the targeted traits and that the observed variance is more likely to be related to the actual characteristics of the individuals being measured rather than method that is used. The validity means that what we are wanting to be measured, the trait in this instance, is actually being correctly measured so if you have stronger correlation scores between measures of the same construct that means you have good construct validity. #13 Which of the following sets of response options would most likely be a problem? ⁃ The correct answer is favorite color: red, white, blue. This is the correct answer because this option is not very comprehensive. If the question asked what your favorite color was and it was something other than red, white or blue you would not be able to answer the question. #15 A researcher may need to use reverse scoring when ⁃ Correct answer is the response options for some questions have the opposite meaning for the concept being measured. Reverse scoring in this case is helpful because it makes sure that the respondent is paying close attention to their answers instead of just answering the same for each one, this helps the researcher distinguish between those who are responding thoughtful and the respondents who are not.

#28 When we say that a measurement instrument measures what it was intended to measure, we are saying that it is ⁃ Correct answer is valid because it is accurately measuring the trait that the researcher intended it to measure. #33 When two observational coders view the same videotaped parent- child interaction separately and then compare the similarity of their resulting scores, they are examining their ⁃ Because we are looking at the reliability between the measures of two raters who separately assessed the same video it is inter-rater reliability. #36 Experimental mortality refers to the problem that arises when sample participants drop out of an experiment in a nonrandom way. ⁃ I chose false but the correct answer is true. Experimental mortality is when sample participants drop out in any way random and nonrandom. #49 The correct answer is check that your treatment and control samples are similar in ways you can identify. If you don’t use random assignment, you may not be able to rule out alternative explanations for your results so it is important that you find similarities in your groups that are identifiable. You could use other strategies to maximize the comparability of the treatment and control groups like matching the participants into groups based on any relevant characteristics like gender or age. #50 The correct answer is false. I think I just read the question wrong. A good research design is NOT the only way to find good answers to important questions there are many other ways to find good answers to your questions. #1 Someone is taking a psychological assessment for the second time. The first time they took the assessment, they simply guess at the answers. The second time, they remember how they answered before, and answer the same way in order to be consistent. The test will probably be ⁃ The correct answer is reliable but not valid. This is the right answer because the test is reliable but the validity of the test is compromised because it is not actually measuring what we want it to measure because the participant is not answering in an honest way but
