The class width is the difference between class boundaries may or may not be the same as class limits. The definition of class width is. The answer is 11.
Enter those values in the calculator to calculate the range the difference between the maximum and the minimum where we get the result of 52 max-min 52 To calculate the width use the number of classes for example n 7.

20-10 1 11. 8 Size of class Derived. Thus the class size would be calculated as.
Hence class width for each class in this example is 10. The size of the class 30-40 is the difference between 30 and 40 which is 10. No matter which class we analyze in the frequency distribution well.
Size of class Base. 24 Size of object d. Find the data range by subtracting the minimum data value from the maximum data value.
