# Basic statistics

The Basic statistics view provides summary statistics about the data in a selected column.

The Basic statistics view in the results pane is accessed by right-clicking a cell in the grid and then selecting Quick analysis of [COLUMN_LABEL] > Basic statistics from the menu.

If a find expression is in effect in the grid, then two columns are shown: one giving the statistics for the entire table, and one giving the statistics for only the highlighted subset of the table. If you change the find expression in the grid, the second column will update automatically.

Note: In this topic, [COLUMN_LABEL] represents the label of the column in which the selected cell is located. Figure: Basic statistics view in the results pane of the TRS and the MLW
