A High School Longitudinal Survey Dataset is presented and one of the variables socioeconomic status has been assessed. The mean of the Socioeconomic status composite is 0.0545 (0.78061 SD).

a) Describe what each of the variables measures.

b) Describe the unit of analysis.

c) Describe and explain the measurement levels for each variable (i.e., nominal, ordinal, interval, ratio).

d) Explain how you might conceive these variables to be used to answer a social change question. What might be the implications for social change?
