# 1 question multiple choice quiz – SPSS

Multiple Attempts In Weeks 4 and 5, you calculated Cronbach’s coefficient alpha and item statistics for the six items in your dataset that are on the Risk-Taking scale, R1–R6. Refer back to the output you obtained. It shows the item-test correlation for each item. Now calculate the mean and standard deviation for each item. Click on ANALYZE>DESCRIPTIVE STATISTICS>DESCRIPTIVE. Move the items R1 through R6 into the VARIABLES box and click on OK. You will see the minimum, maximum, mean, and standard deviation for each item. In the quiz, you see the item characteristic curves (ICC) for these items: R3: I’m willing to take real chances to get ahead financially R5: Being too conservative with your investments can cause financial problems R6: Running a business is something that I think of as interesting and exciting Note: Please refer to the following graphs to complete the question. Not allowed. This test can only be taken once. This test can be saved and resumed later.

### QUESTION 1

(Reference for Week 4 Attached):

For this Knowledge Assessment, you perform test item analysis on the MoneyData dataset provided in the Week 2 Learning Resources.

The data file includes a six-item scale to measure financial risk-taking tendencies:

• R1: I’d rather run my own business than work for someone else
• R2: I don’t mind risking large amounts of money if there is a good chance I can come out ahead
• R3: I’m willing to take real chances to get ahead financially
• R4: I get bored unless I’m taking some risks with my career
• R5: Being too conservative with your investments can cause financial problems
• R6: Running a business is something that I think of as interesting and exciting
