If they are numeric, classification variables will tend to have relatively few distinct values. Pa_history and Mo_depression are both assigned this role. ƒ Group analysis by variables are also discrete, numeric, or character—variables which define groups in the data. When a variable is assigned this role, the analysis is repeated for each group defined by the variable. For example, if a variable, sex, with values male and female was assigned this role, the analysis would be repeated for males and females separately.

Reply Yes to Would you like to replace the results from the previous run? 1; they indicate that both sets of guesses contain a number of possible outliers and also that the guesses made in meters are skewed (have a longer tail) and are more variable than the guesses made in feet. We shall return to these findings in the next subsection. 1 Box Plots of Room Width Guesses Made in Feet and in Meters (after Conversion to Feet) Constructing Histograms and Stem-and-Leaf Plots The box plot is our favorite graphic for comparing the distributional properties of a measurement made in different groups, but there are other graphics available within distribution analysis: histograms and stem-and-leaf plots.
