Project 4

Question 1

Dataset: Project 4 Q1 data.sav

The data file contains the test scores for 20 KSU psychology students who took an exam on t test and an exam on regression.

1. Suppose we know that the among all psychology majors, the mean score on the t test exam is 70 . Please perform the appropriate procedure in SPSS to test whether psychology students do better or worse on the t test exam compared to the national average.
   1. What is your null hypothesis? What is your research hypothesis? (2 pts)
   2. Attach the SPSS output. (4 pts)
   3. Report the findings in APA style. (4 pts)
2. Suppose we know that the among all psychology majors, the mean score on the regression exam is 68 . Please perform the appropriate procedure in SPSS to test whether KSU psychology students do better or worse on the regression exam compared to the national average.
   1. What is your null hypothesis? What is your research hypothesis? (2 pts)
   2. Attach the SPSS output. (4 pts)
   3. Report the findings in APA style. (4 pts)

Question 2

Dataset: Project 4 Q2 data.sav

A data analytical company recently purchased SPSS license for all of their data analysts. Because few data analysts were ever exposed to SPSS before, the company delivered a one-week SPSS training to 38 data analysts. Before the training, the analysts were required to take a quiz for which they had to rely on hand calculations. After the training, the analysts took the quiz again with the help of SPSS. Please perform the appropriate procedure in SPSS to test whether the trainees’ data analytical performance changed significantly after the SPSS training.

1. What is your null hypothesis? What is your research hypothesis? (2 pts)
2. Attach the SPSS output. (4 pts)
3. Report the findings in APA style. (4 pts)

Question 3

Imagine you were a job candidate trying to pitch your skills to a potential employer. Would you be more likely to get the job after giving a short speech describing your skills, or after writing a short speech and having a potential employer read those words? Two psychologists wanted to know whether a person’s speech (i.e., vocal tone, cadence, and pitch) communicates information about their intellect better or worse than their written words (even if they are the same words as in the speech).

The psychologists randomly assigned 39 professional recruiters for Fortune 500 companies to one of two conditions. In the audio condition, participants listened to audio recordings of a job candidate’s spoken job pitch. In the transcript condition, participants read a transcription of the job candidate’s pitch. After hearing or reading the pitch, the participants rated the job candidate’s intellect, with higher scores indicating the recruiters rated the candidates as higher in intellect. The participants also rated their overall impression of the job candidate (higher score indicating greater overall impression). Finally, the participants indicated how likely they would be to recommend hiring the job candidate (0 - not at all likely, 10 - extremely likely).

1. Please perform the appropriate procedure in SPSS compare participants in the audio condition to participants in the transcript condition on the Intellect_Rating variable.
   1. What is your null hypothesis? What is your research hypothesis? (2 pts)
   2. Attach the SPSS output. (4 pts)
2. Please perform the appropriate procedure in SPSS compare participants in the audio condition to participants in the transcript condition on the Impression_Rating variable.
   1. What is your null hypothesis? What is your research hypothesis? (2 pts)
   2. Attach the SPSS output. (4 pts)
3. Please perform the appropriate procedure in SPSS compare participants in the audio condition to participants in the transcript condition on the Hire_Rating variable.
   1. What is your null hypothesis? What is your research hypothesis? (2 pts)
   2. Attach the SPSS output. (4 pts)
4. Prepare an APA-style results paragraph describing the results of the analyses performed above. (12 pts)
