• Nominal variable: Record everyone’s eye color and create a frequency table, a pie chart, and a one-variable bar chart to display the information.

• Numerical variable: Each person provides information about his or her mother’s age at the time of that person’s (the respondent’s) own birth. Find the mean, median, mode, range, variance, and standard deviation of this distribution. Chart it in a histogram and in a boxplot. Discuss how the boxplot and the histogram are different.
