1. In a recent survey on the family size of community A, 20 couples are asked how many children they have. The following are their answers: 0, 2, 6, 2, 3, 1, 3, 4, 5, 4, 3, 1, 2, 5, 3, 0, 2, 1, 3, 4. (Note: You should solve this problem by using the SPSS program.) (Be sure to include the relevant SPSS output in your answer.)

Construct a frequency distribution table for this set of outcomes including f (frequency), % (percentage), and cum. % (cumulative percentage). (5 points)

Have SPSS produce the measures of central tendency (including the mode, the median, and the mean) and the measures of dispersion (including the range, the IQR, the variance, and the standard deviation for this distribution. Include the SPSS output that helps you find your answer. For the measures reported in the table from SPSS, highlight or type the requested values. For the measure(s) that are not produced in SPSS, type the value(s) in your answer.

Do you think that this distribution is a normal distribution? Have SPSS produce a histogram with a normal curve included and the values of skewness and Kurtosis for this distribution. How does the information (i.e., the graph, the values of skewness and Kurtosis, or any other information) that you obtain from SPSS help you reach your conclusion? (8 points)

2. Use the gsslab.sav to examine the following questions. Include the SPSS output (only the tables/figures that help you find your answer) in this document.

Construct a frequency table for respondents' weekly working hours ("hrs1"). Is this variable nominal, ordinal, or interval/ratio? How many respondents provided valid data for the table? What is the percent of valid responses among the total? How many respondents did NOT provide data? (10 points)

2

How many respondents worked less than 10 hours per week? What is the proportion of respondents who worked for 40 hours a week? What is the percent of respondents who worked more than 60 hours a week? (9 points)

Explore the variation of respondents' weekly working hours across gender groups. Have SPSS produce the values of mean and the standard deviation for each gender group. Choose an appropriate graph to demonstrate gender differences in terms of their weekly working hours. Report the values of mean and the standard deviation produced in SPSS and explain the differences between men and women regarding their weekly working hours. (11 points)

3. Use the gsslab.sav to examine the time respondents spent in watching TV each day ("tvhours"). Include the SPSS output (only the tables/figures that help you find your answer) in this document.

Compare the distribution of respondents' TV hours for males with that of females. Report the values of mean and the standard deviation produced in SPSS and explain the differences between men and women regarding their time spent watching TV.

3

Compare the distribution of respondents' TV hours for those who are married with that of singles. Report the values of mean and the standard deviation produced in SPSS and explain the differences between married individuals and singles regarding their time spent watching TV. (Hint: Use the "absingle" as the grouping variable.)
