Determine the preferred width of each class if you use 8 classes, a high of 87, and a low of 2. (this is a statistics question)

A. 15
B. 13
C. 11
D. 10

Respuesta :

Answer:

11 ; C

Step-by-step explanation:

To get the class width, we start by finding the range of the data set

That will be; the highest number - the smallest number

= 87-2 = 85

We proceed by dividing the number of classes we want by this number

That will be 85/8 = 10.625

We now proceed to approximate this value to the nearest whole number = 11

Hence , 11 is the class width to use
