Adata set consists of 83 observations. how many classes would you recommend for a frequency distribution?

solution:

First determine number of classes using 2 to the k rule

2⁶ = 64

64 is less than 83,  

So,

6 classes is not enouth.

Try the next highest number = 2⁷ = 128

128 is greater then 83  

So,  

The recommended number of classes is 7.

i suppose it should be (y=2x-5)

step-by-step explanation:

hope this !
