Social Studies 306

Fall 1998

Assignment 4

Due: October 29, 1998

Use the original data set, 746.SAV in the 0:\STUDENTS\PUBLIC\306DATA directory for this assignment. The assignment asks you to construct some tables after using the Select cases, Recode, and Compute procedures in SPSS. When you get the output, write the comments on the printed copy in pen or pencil. Alternatively, you can enter the comments on the computer, in the SPSS output file, or in a Word file.

Note: Before producing the tables for this assignment, set the options so that SPSS commands that you enter into the computer are shown on the SPSS output. In order to do this, make sure the Display commands in the log at the lower left of Edit – Options – Navigator is checked.

Questions

1. Recode the variables coffee and drunk so that the new codes match the actual values of the variables as closely as possible. After recoding, obtain frequency distributions for both of the recoded variables, along with the mean and standard deviation for each. Briefly describe the results.
2. Do those who work more hours on the job study fewer hours? In order to examine this, recode each of sthours and jobhours into three or four categories and give the crosstabulation table showing the relationship between the two. From this table, write a note commenting on whether or not those who work more hours on the job study fewer hours.
3. Use the Compute procedure to compute the number of children per respondent. Obtain a frequency distribution for the number of children per respondent, along with the mean and standard deviation for this variable. Also obtain a bar chart for the number of children per respondent. Write a short note describing the distribution of the variable.
4. The variables from regret through law are each coded on a scale from 1 (not at all) through 3 (a lot). A scale concerning problems resulting from alcohol consumption can be obtained by summing these seven variables. Use Compute to do this and obtain a frequency distribution along with the mean and standard deviation for this scale. Use the Means procedure to examine whether there is a relationship between this scale and (a) alcohol use (question 23) and (b) whether parents permitted underage drinking (question 28). Briefly describe the results.
5. Use Select cases and Frequencies to produce a frequency distribution for the number of children per respondent for respondents with children. Also obtain the mean and standard deviation and write a short note describing the distribution.

6. In the previous computer assignment, you examined whether or not having a job is associated with a difference in the number of hours spent at various activities. The largest differences in hours were related to study hours, hours at housework, and hours with dependents. Use the Select cases procedure to examine how this pattern of differences may differ between males and females. First select males and examine how the mean hours at these three activities differs for males with and without a job. Then do the same for the females. Write a short note describing the results.
