Box Plots
The command Math/Statistics/Box Plots calculates and displays the box plots of the selected data. The data can be selected either by ticking off the corresponding variable names or by marking the data cells which are to be included in the box plot. After issuing this command, the data matrix is displayed in a numerical table where you have to mark the elements to be included in the calculations (type A and B, red and blue).
Then click the button Frequencies of Marked Data to calculate the percentiles and frequencies of the selected data. As an alternative, you can calculate the frequency tables of all variables by clicking the button Frequencies of Columns. In this case you need not mark any data at all.
