Answer briefly question 1-15

1. Analysis of one variable at a time is often referred to as what type of analysis? 2. What are the two parts of the SPSS Statistics Viewer called? 3. What is a frequency distribution? 4. In a frequency distribution, what information does the column labeled "Frequency" contain? 5. In a frequency distribution, what information does the column labeled "Valid Percent" contain? 6. Is a frequency distribution generally preferred for continuous or discrete variables? Why? 7. List the measures of central tendency and dispersion appropriate for variables at each of the following levels of measurement: a. Ordinal b. Nominal c. Interval/ratio 8. List the measures of central tendency and dispersion appropriate for each of the following types of variables: a. Discrete b. Continuous 9. Calculate the mode, median, mean, and range for the following distribution: 7, 5, 2, 4, 4, 0, 1, 9, 6. 10. If Q1 (Quartile 1) = 25 and Q3 (Quartile 3) = 40, what is the interquartile range for the distribution? 11. Is the standard deviation a measure of central tendency or dispersion? 12. In general terms, what information does the standard deviation tell us? 13. Explain why, for certain GSS variables, a large number of the responses may be labeled "missing," coded as IAP. 14. In order to save or print output, which SPSS Statistics window should be the "active window"? 15. In order to save your data file, which SPSS Statistics window should be the "active window"?
