Abstract: sumscale generates new variables by combining the scores of a set of ordinal/dummy variables of an underlying factor/construct. There are two ways in which sumscale combines the scores of a set of ordinal variables/items: 1) take the average and 2) take the sum. The first option is the default of sumscale. The second option can be chosen by adding fsum as shown below. sumscale displays also some descriptive statistics as well as the Cronbach Alpha coefficient of reliability for the newly generated summated scale/s. sumscale allows also for combining the scores of a set of dummy variables. This is simply done by taking the sum of the scores. This option can be chosen by adding dummy. For the resulting variables the program displays the descriptive statistics and the Kuder-Richardson coefficient of reliability.
