This article explains how to standardize values in a block.
 

1. Select a block of values in the spreadsheet, right-click, 

2. Select either Fill/Standardize Block - Standardize Columns or Fill/Standardize Block - Standardize Rows from the shortcut menu. The standardized values are computed as follows:

Standard Value = (raw value - mean of highlighted row/column)/standard deviation.

Note: Selected variables can also be standardized by selecting Data|Standardize. This procedure operates independent of the currently selected block, but takes into account the current case selection conditions and weights.
