Exploring Data with the Distribution Platform
Overview
This chapter illustrates the use of the JMP Distribution platform, which can be used to calculate means, standard deviations, and other descriptive statistics for quantitative variables; and construct frequency distributions for categorical variables. The Distribution platform can also be used to test for normality and produce stem-and-leaf plots. Once data are entered into a JMP data table, features of the Distribution platform can be used to screen for errors, test statistical assumptions, and obtain simple descriptive statistics.
