# About row multipliers (frequency weights)

If each row in a data table represents more than one observation, it may be appropriate to use a row multiplier. A row multiplier ensures that charts, statistics, and models are calculated from the number of observations rather than number of rows; without a row multiplier, also known as a frequency weight, it is assumed that each row represents one observation.

To apply a row multiplier to a table:

- In the Summary view, select the column you wish to use as a row multiplier
- Choose Column > Treat Column Data As > Row Multiplier

A row multiplier can also be applied via the Table menu.

The column used as the row multiplier (typically named count) will appear in the table in bold. The other columns will have this row multiplier applied when performing all tabulations and statistics.
