I am currently trying to calculate mean and standard deviation for a numeric field, using summary statistics. I want the summary statistics table to include the values from four other fields so that I can merge summary statistics from different shapefiles, so I include those fields in the "case field" window (all features within each file have the same values within the four case field, some text, some numeric). However, when I run summary statistics the resulting table shows up empty except for one row that displays the field names. I've had this problem before, but apparently fixed it when I added my data to a new map. However, I tried that just now but it didn't work. I'm obviously doing something wrong... any ideas?
