Adding summary statistics to a numeric variable
You can show a summary statistic of the values in a numeric variable (such as the mean, minimum, or maximum) instead of grouping the values into bands. For example, the visits variable in the Museum sample data set is a numeric variable that stores the number of times respondents have visited the museum before. You can show a summary of the values in the variable.
UNICOM Intelligence Reporter does not add summary statistics to numeric variables that do not have any bands or other statistics defined. You must manually set up these definitions if they do not already exist. The
Unable to Add Variable dialog displays if variables do not have statistics defined. If you want to mix both approaches, to include bands and also a mean value, create bands (see
Creating bands) and then insert the statistics as described here.
