Data Collection Figure 1. Chart on the Percentage of Observers: Female vs. Male in 2008 (Source: Lind, Marchal, and Wathen, 2008, Statistical Techniques in Business and Economics) Descriptive Statistics 2 In the preceeding page is a pie chart that shows a set of nominal data of respondents according to gender.
