Use GSS10SSDS to study the number of hours that blacks and whites work each week. The variable HRS1 measures the number of hours a respondent worked the week before the interview. Use the Explore procedure to study the variability of hours worked, comparing blacks and whites (RACECEN 1) in the GSS sample.
a. Is there a difference between the two groups in the variability of work hours?
b. Write a short paragraph describing the box plot that SPSS created as if you were writing a report and had included the box plot as a chart to support your conclusions about the difference between blacks and whites in the variability (and central tendency) of hours worked.
