You need to compute the variance or standard deviation of each set of data. The higher the variance, the greater the variability. Consult your statistics or probability theory textbook for the formula. Also, there is a function for this in Excel and other programs.

just subtract lowest from highest scores for each person to find variability
for robin it would be 139-122 or 17
for kim it would be 140-127 or 13
robin has greater variablility
