  1. POLI 30: MOCK MIDTERM EXAM Spring 2008

  2. Define the mean, median, and mode. When will they all • have the same values? How do they differ when the • distribution of a variable is skewed to the right? • What does the standard deviation indicate? Give a hypothetical example. • What is a “standard score”? What uses might it have? • Define three measures of dispersion. • Explain the idea of “dependent” and “independent” and “intervening” variables.

  3. Mock Midterm (continued) • What are the special properties of the arithmetic mean? • What is the formula for computation of the standard deviation? • Find the median and compute the mean and standard deviation (for a given set of numbers—as in Homework #1). • What is chi-square? Define in words and give computing formula.

  4. Mock Midterm (continued: Readings) • How and why does Peter Smith select levels of measurement for his study of democracy in Latin America? Does he use more than one level? • Does Smith observe any relationship between “independent” and “dependent” variables? If so, where and what? • 3. How does Roy Licklider select levels of measurement for his analysis of civil wars? • 4. Do you think Licklider’s indicators are valid and reliable? Why or why not?
