Document Summary
Textbook: measures of central tendency statistics that summarize a distribution of scores by reporting the most typical, average, or central value of the distribution and have three common measures . The index varies from 0. 00 (no variation) to 1. 00 (maximum variation) K= the # of variable response categories. Pct2 = the sum of the squared % of cases in the variable response categories. In the sample, 92. 5% of people reported they did not own a gun in their home, while 7. 5% said they did. In the sample, most people said they did not own a gun, despite what the stereotype says. In some cases: median, for skewed variables (textbook: for ordinal -- iffy) Rarely: mode (often more useful for categorical variables: measures of dispersion. Capture the variability, or dispersion, around the center. Also, used: range, interquartile range (textbook: iqr for ordinal -- iffy)
