SPSS Problem #7 (SPSS7)

Sampling and Sampling Distributions

Â

Recommended prior reading: Social Statistics for a Diverse Society, p. 231-234

Â

To complete the following exercise, use the GSS 2010 data file

Please turn in both your SPSS Output and a Word document/PDF in Blackboard.

Â

1. Choose an interval-ratio level variable and produce its univariate statistics

with the Descriptives command (Analyzeâ†’Descriptive

Statisticsâ†’Descriptives).

a. Under Options, select the mean, standard deviation, minimum and

maximum values, and the standard error of the mean (S.E. mean).

2. Select 10%, 25%, 50%, and 75% random samples and run the same

Descriptives command for your chosen variable each time.

a. You may want to check the â€œSPSS Demonstrationâ€ on p. 231-234 to

learn how to get random samples in SPSS.

3. In your Word document, write a paragraph or two comparing the

descriptive statistics for your random samples with that of your full sample.

a. Of particular interest, note how the standard error of the mean

changes for each random sample. What does this indicate? (Hint:

look back at p. 226-227 and think about how the sample size affects

the standard error of the mean)

the 90% confidence interval means for each of these variables. In
