Descriptive Statistics - Introductory Overview

Descriptive statistics are calculated separately for each variable, and they provide such basic information as the mean, minimum and maximum values, different measures of variation, as well as data about the shape of the distribution of the variable. Those statistics are reviewed in this overview (see also the Descriptive Statistics dialog for a complete listing). For the descriptive statistics procedure, you can select all variables in the current data set and a sequential table of "descriptives" for the consecutive variables will be generated (one row per variable). The measures of variation include the standard deviation, and the standard error. Numerous tests of whether the distribution of variables follows the normal distribution are also provided (refer to the Descriptive Statistics dialog for a complete description of all options).
