The Means procedure is used to calculate the average value of a variable for each group. In order to calculate an average, the variable must be measured on an interval or ratio scale, as these scales allow for meaningful numerical comparisons and calculations. Nominal and ordinal scales do not allow for such calculations, as the categories or levels are not quantitatively comparable. Therefore, the lowest level of measurement permissible for the variable that is averaged in the Means procedure is interval/ratio.
