the names public B. The researchers knows the identity of the participants but changes their names in the data files and research reports C. The researcher does not know the identity of the participants D. All of the above 22. A researcher has created a type of ruler that measures a person’s shoe size. According to this researcher’s theory, scores on this measurement instrument are an indicator of interpersonal social skills. Most psychologists would probably expect to find that this new measure is ________ and __________. A. highly reliable; valid B. unreliable; invalid C. highly reliable; invalid D. unreliable; valid Use this information for the next two [2] questions. A researcher is planning a study on memory using a three-way factorial design. The independent variables will be type of material [words versus object], amount of material [20 versus 40 versus 60 items], and amount of time to study [2 minutes versus 5 minutes]. 23. This study would be described as a __________ factorial design. A. 2 x 2 D. 3 x 3 B. 2 x 3 E. 2 x 2 x 2 C. 2 x 3 x 2 24. How many experimental conditions are in the study? A. 3 B. 7 C. 12 D.

In a factorial design, a “main effect” is A. the effect of one independent variable on another independent variable B. the effect of one independent variable on the dependent variable C. the effect of one independent variable at a single level of another independent variable D. a finding that is theoretically interesting, intriguing or unexpected . Computer applications: 26. You have the choice of a] receiving \$50,000 per day for a month or b] receiving a penny on day one of the month and having the amount you receive double each day of the month. Which choice will result in more money at the end of a month? A. Receiving \$50,000 per day B. Receiving a penny on day one which then doubles each day C. The end result will be the same after 30 days. D. None of the above as I already have too much money! 27. If a researcher wanted to know how the performance of each subject in her experiment compared to the group of subjects, what Excel function should she use? A. Array B. PercentileRank C. Percentile D. Compare E. COUNT F. COUNTIF 28. In Excel, I need to write a formula that works this way: If cell A1 is less than 20, then multiply it by 1, If A1 is greater than or equal to 20 but less than 50, then multiply it by 2 If A1 is greater than or equal to 50 and less than 100, then multiply it by 3 And if A1 is great or equal to than 100, then multiply it by 4 Which formula below solves this problem? A. =IF(A1<20, A1*1, IF(A1<50, A1*2, IF(A1<100, A1*3, A1*4))) B. =IF(A1<100, A1*3, IF(A1<50, A1*2, IF(A1<20, A1*1, A1*4))) C. =IF(A1>=20, A1*1, IF(A1>=50, A1*2, IF(A1>=100, A1*3, A1*4))) D. =COUNTIF(A1<20, A1*1, IF(A1<50, A1*2, IF(A1<100, A1*3, A1*4))) E. =COUNTIF(A1<100, A1*3, IF(A1<50, A1*2, IF(A1<20, A1*1, A1*4))) F. =COUNTIF(A1>=20, A1*1, IF(A1>=50, A1*2, IF(A1>=100, A1*3, A1*4))) 7 Distributing prohibited | Downloaded by Poo Pee ([email protected])

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
