Question 2

Suppose that you have a data set of 512 observations and the data values range from 36 to 187. What classes would you choose for this data set? Explain why you would choose these values.
 
  What will be an ideal response?

Answer to Question 1

TRUE

Answer to Question 2

For n=512 values, 9 classes would be about the right number of classes based on the 2k  n rule. Then the class width should be about (187-36 )/9 = 16.8, which should be rounded to 20. So the classes should start at 20 or 30 to be low enough to contain the lowest value. So one way to do the classes is:
20 to < 40
40 to < 60
60 to < 80
80 to < 100
100 to < 120
120 to < 140
140 to < 160
160 to < 180
180 to < 200
This is 9 classes, all inclusive, mutually exclusive, equal width, and contains all the data values.
