1 appears twice
2 appears five times
3 appears four times
4 appears six times
5 appears eight times
6 appears six times
7 appears six times
8 appears five times
9 appears five times
10 appears four times
11 appears once
13 appears four times
14 appears six times
15 appears six times
16 appears six times
17 appears three times
18 appears four times
19 appears two times
20 appears five times
21 appears two times
22 appears one time
23 appears four times
24 appears two times
26 appears four times
27 appears one time
28 appears four times
29 appears one time
30 appears two times
31 appears three times
32 appears two times
33 appears five times
34 appears five times
36 appears one time
From the counts, we can see that the number 5 appears most frequently, with a count of eight times. Therefore, the mode, representing the number of years the Supreme Court justices served most often, is 5.
