Use the 2004 GSS data for this assignment. This is the same dataset used for SPSS Assignment #1. It is available on the course website in the "SPSS Labs → SPSS Lab 1" folder and is called GSS_SPSS1.

You want to determine whether the economic conditions in which a person grows up influence the number of children the person has as an adult. The variable childs represents the number of children for each respondent, a quantitative variable. The variable incom16 represents the childhood economic background of each respondent, coded as an ordinal variable.

As a first step, an analysis of variance (ANOVA) tests whether the average number of children differs among adults of different childhood economic backgrounds.

For questions 1 through 6 provide only the answers that are requested. Please put clearly labeled SPSS syntax and output in an appendix.

1. Include in your analysis only adults of age 25 or older.
2. Create a line or bar graph representing the average number of children by each level of adult’s childhood economic condition. For each group, label the mean number of children.
3. For each group, provide the mean number of children (again), the standard deviation, standard error, and the 95% confidence interval for the mean. Why is the least precise confidence interval for the "far above average" group? How could you make the confidence interval more precise for this group?
4. The GSS provides random, independent samples for each group. Are the other two assumptions for an ANOVA met? Explain your answer. Note: If you refer to SPSS output in this answer, put the output in the appendix.
5. In a brief paragraph, explain your conclusion from the ANOVA using a .05 level of significance. Note: Put the ANOVA table in the appendix.
6. If appropriate, conduct multiple comparisons (post hoc tests) for pairs of groups using the Bonferroni method. Do not provide the entire table from SPSS because it might be large. In a brief paragraph, simply discuss a few of the comparisons.
7. Put clearly labeled SPSS syntax and output here (appendix).
