Summarize Columns
The Tables > Summary command calculates various summary statistics, including the mean and median, standard deviation, minimum and maximum value, and so on.
Summary tables have the following characteristics:
•
A single row exists for each level of a grouping variable that you specify. If no grouping variable is specified, a single row exists for the full data table.
•
When there are several grouping variables, the table contains rows for each combination of levels of all the grouping variables.
•
In addition to one column for each grouping variable, the table contains frequency counts in a column named N Rows with counts for each grouping level.
•
The summary table can be linked to its source table. When you select rows in the summary table, the corresponding rows are highlighted in its source table.
•
If the source table’s column(s) contain value labels, the value labels are displayed in the new table.
•
A summary table is not saved when you close it unless you select File > Save As to give it a name and location.
