• Explain the differences between dispersion and deviation and discuss how they compare to measures of central tendency.
• Define standard deviation, index of dispersion, and range. Discuss why they are not as clear as measures of central tendency.
• For the variables Home (p. 89), Arrest (p. 107), Education (p. 101), identify the correct measure of dispersion (standard deviation, index of dispersion, or range) for each variable and explain why it is appropriate. Report the values for the measure of dispersion for each variable.
