A data set consists of 83 observations. How many classes would you recommend for a frequency distribution?
Step 1 of 3
Step1 of 2:
From the given problem we have total number of observations = 83.
We need to find the classes for a frequency distribution.
Step2 of 2:
We have totally 83 observations, by using 2 to the power ‘k’ rule.
The 25 = 32, which is less than 83, so 5 classes are not enough.
Take the 26 = 64, which is less than 83, so 6 classes are not enough.
Take the 27 = 128, which is greater than 83.
Hence, I will recommend 7 classes.
