SOLUTION

TO FILL IN THE BLANK

For the class interval 72 - 93 , the class width is___

CONCEPT TO BE IMPLEMENTED

Class Interval :

When the number of sample values are large in number and are in wide range, then the whole data is divided in a number of several groups according to the size of the sample. Each of these groups, made as above, is known as class interval

Class Width :

Class Length or Class Size or Class Width of the class interval of any class is defined to be the difference between the lower and upper class boundaries ( not class limits) of that particular class interval.

Class length = Upper Class boundary - Lower class boundary

EVALUATION

Here the given class interval is 72 - 93

Upper Class boundary = 93

Lower class boundary = 72

Hence the required class width

= Upper Class boundary - Lower class boundary

= 93 - 72

= 21

FINAL ANSWER

For the class interval 72 - 93 , the class width is 21
