Open the data file "cjgss.

Open the data file “cjgss.sav1”, and 1) examine the variable labels and level of measurement of all variables in the file, and 2) obtain the frequency histogram and Statistics table for the variables “age” and “edu” (The table should include the basic measures of central tendency and dispersion; see the steps in SPSS provided on Page V in the Module 4 lecture.).

Save your output file (.spv). Attach the file to your initial post in the Discussion Forum and discuss the following:

1. What are the units of analysis in this dataset and how many cases are in the data file?
2. What is the average age and years of education of the survey respondents?
3. What are the most frequent age and years of education completed in the survey sample?
4. Do their frequency distributions appear to be approximately normal/symmetric?
5. Does one distribution appear to be more skewed than the other? Describe how. Calculate the low and high points between which about two thirds of the education fall.
