Find Skp for the following set of observations.
17, 17, 21, 14, 15, 20, 19, 16, 13, 17, 18

#### Solution

sum"x"_"i" = 17 + 17 + 21 + 14 + 15 + 20 + 19 + 16 + 13 + 17 + 18 = 187

Here, n = 11

Mean = (sum"x"_"i")/"n"

= (187)/(11)

= 17

Mode = Observation that occurs most frequently in the data
= 17

Skp = ("Mean"-"Mode")/"S.D."

= (17-17)/"S.D."

= 0/"S.D."

= 0
