A basic approach may be to standardize them. Then you can see how many standard deviations they are from the mean. Though of note, many times the mean can be a poor measure of central tendency in small samples due to unruly pull of outliers.

Psych Numbe of active clients Number of attended appointments Number of missed appointments % of missed appts

1 141 1033 41 3.8

2 78 616 41 6.2

3 11 156 4 2.5

4 117 711 42 5.6

5 117 858 61 6.6

6 114 730 33 4.3

7 108 627 26 4.0

Average 98 676 35 5.0

and "attendance" (missed appointments / attended appointments) using a

Chi square test. If the association is statistically significant you could inspect

the standardized cell residuals. Residuals larger than 1.96 or smaller than -1.96

are taken as indication of a "signifcant" deviation from expected cell frequencies.
