Frequency requency Relative Rating 4 2 Total

Explanation / Answer

Solution:
Frequency is the rate at which something occurs over a period of time in given sample.
step1: sort the sample
1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,3,3,3,3,3,4,4,4,4,4,4,5,5,5,5
Count the 1's in sorted data = 14
Count the 2's in sorted data = 7
Count the 3's in sorted data = 5
Count the 4's in sorted data = 6
Count the 5's in sorted data = 4
So frequency table is

Relative frequecny for 1's is. = 14/36 = 0.3888
Relative frequency for 2's is. = 7/36 = 0.19444
Relative frequency for 3's is = 5/36 = 0.13888
Relative frequency for 4's is = 6/36 = 0.16666
Relative frequency for 5's is = 4/36 = 0.11111
