In constructing a frequency distribution, the approximate class width is computed as
|
|
(largest data value-smallest data value)/number of classes
|
|
|
(largest data value-smallest data value)/sample size
|
|
|
(smallest data value-largest data value)/sample size
|
|
|
largest data value/number of classes
|
Explanation:
Detailed explanation-1: -A class interval, or class width, can be determined by subtracting the lower limit of a class from the lower limit of the next higher class. To convert a frequency distribution to a relative frequency distribution, divide each class frequency by the sum of the class frequencies.
Detailed explanation-2: -The size, or width, of a class interval is the difference between the lower and upper class boundaries and is also referred to as the class width, class size, or class length.
