Jasmin Isom CRIJ 5396 SPSS Statistics Lab Exercise 8.1 (Extra Credit) Dr. Royal December 4, 2023 INDEX 1: POLIN The first index is based on two variables contained in your AdventuresPLUS.SAV (or Adventures.SAV) data file, POLABUSE and POLATTAK. Simply follow the steps below and supply the information requested. 1. What does the variable POLABUSE measure? Should police be authorized to use force if a citizen said vulgar or obscene things 2. What does the variable POLATTAK measure? Should police be authorized to use force if a citizen attacking policeman with fists 3. List the values and labels for POLABUSE and POLATTAK. 0=IAP, 1=Yes, 2=No, 8=DK, 9=NA Now define 0, 8, and 9 as “missing” for the variables POLABUSE and POLATTAK. Our new variable/index will be named POLIN (for POLice INdex). POLIN scores are as follows: 0— “Approve/Yes” in both cases 1— “Conditional Approval/Yes” in one case but not the other 2—” Disapprove/No” in both cases 4. The Lower (higher/lower) the index score, the more the respondent agrees that there are situations in which they would approve of a police officer striking an adult male citizen. 5. The Higher (higher/lower) the index score, the less the respondent agrees that there are situations in which they would approve of a police officer striking an adult male citizen. Now, compute new variable/index POLIN. (Hint: Click Transform → Count.) Then, define your new variable. (Hint: Access the Variable View tab, and then set decimals, width, values/labels, and measure.) 6. Access the Data View tab. Use the information in the matrix to complete the first two columns indicating the values for the variables POLABUSE and POLATTAK (Respondents 1–3, 6– 8). After completing the first two columns, use the information to fill in the expected index score for each case. Now, compare the expected index score with the actual POLIN score for each case. Based on this “test,” use the space below to indicate whether your index appears to have been completed properly or whether you need to go back and reconstruct the index. POLABUSE POLATTAK Expected Index Score Actual POLIN Score

1. 0 0 Missing Missing 2. 2 2 2 2 3. 2 1 1 1 4. 2 1 1 1 5. 2 1 1 1 6. 0 0 Missing Missing 7. 2 1 1 1 8. 2 1 1 1 Run frequencies for POLIN, and attach your output to this sheet. 7. Of those who answered, 9.3 % received a score of 0 on the index. 77.4 % received a score of 1 on the index. 13.2 % received a score of 2 on the index. INDEX 2: POLFORCE Now, it is time to compute an index on your own. Create a more complex index (POLFORCE) based on the following four variables: POLABUSE, POLATTAK, POLESCAP, and POLMURDR. Be sure to define 0, 8, and 9 as “missing” for each variable before you begin. 8. After you construct and define your index, run frequencies, and attach your output to this sheet. Then, describe your findings below. What does this index tell us about Americans’ attitudes toward the use of force by police officers? INDEX 3: CONSTRUCTING AN INDEX OF YOUR CHOICE Choose variables from the Adventures.SAV (or, of course, AdventuresPLUS.SAV) file, and create an index of your choice. When you are finished, answer the following questions: 9. What variables did you choose, and why? 10. After you construct and define your index, run frequencies, and attach your output to this sheet. Then, describe your findings below. After you are done, be sure to save the indices you created in this lab exercise in your AdventuresPLUS.SAV file so we can use them in later analyses.
