Now, according to the steps mentioned above, first we find the number of variables in the sample (n). Here n = 22
Then we need to arrange the 22 random numbers in ascending order, as shown in the table below.
S. No Random numbers
1 25
2 26
3 28
4 30
5 33
6 35
7 36
8 37
9 39
10 42
11 43
12 44
13 45
14 47
15 52
16 54
17 55
18 58
19 64
20 65
21 66
22 68
Now, we can calculate the positions of decile D1 to decile D9.
(n + 1)
D = 1 × 10th data
1
(22 + 1)
= 1 ×
10
= 23
10
= 2.3rd data
i.e., data between positions 2 and 3:
26 + 0.3 × (28 – 26)
= 26.6
