Introduction

This tool creates a graphical summary report from data including group information. The statistical graphs includes histograms, box charts, and plots of confidence intervals, along with tables of key statistical quantities.

Performing Graphical Summary

Select the input data columns on which you want to perform descriptive statistics.
Choose Statistics: Descriptive Statistics: Graphical Summary to open the dialog.
Select grouping column(s) for Group(s), enter the desired confidence level in the Confidence Level(%) edit box, and then specify the graph layout from the Graph Arrangement drop-down list.
Click OK to perfrom the descriptive statistics and create the graphs.

Dialog Controls

Input	Choose the input column(s). Note that Data Table is also supported.
Groups	Choose the column(s) to divide the input data into multiple groups.
Confidence Interval(%)	Specify the confidence level.
Graph Arrangement	Specify how to arrange the statistical graphs. Separate Graphs: Each variable for each group will be plotted into a separate graph. Each graph includes 3 plots - a histogram with distribution curve, a plot of confidence intervals plot and a probability plot, and 3 tables - "Description Statistics", "##% Confidence Intervals" and "Normality Test". The graph title shows the variable and group information. Per Variable: Each Variable will be plotted into a separate graph. The groups will be plotted into different veritical panels. Each variable includes 3 plots - histogram with distribution curve, a box chart with outliers, and a plot of confidence intervals - and a table summarizing the results by row, showing statistics for each group. Per Group: Each group will be plotted into a separate graph. The variables will be plotted into different veritical panels. Each group includes 3 plots - a histogram with distribution curve, a box chart with outliers, and a plot of confidence intervals - and a table summarizing the results by row, showing statistics for each variable. All in One: All variables and all groups will be plotted into one graph. Each subset(Group*Variable) will be plotted into different veritical panels. This graph includes histograms with distribution curve, box charts with outliers, plot s of confidence intervals, and a table summarizing the results by row, showing statistics for each subset.
