Question

In which of the following, equal interval of each class is must?

Answer 1

Answer:

While arranging large amount of data (in statistics), they are grouped into different classes to get an idea of the distribution, and the range of such class of data is called the Class Interval.

Answer 2

Intervals between classes should be exhaustive, but they should not have to be of equally spaced.

Equal intervals refers to the fact that the gaps between numbers (units) on the scale are the same everywhere.

In statistics, data is divided into classes, and the breadth of these classes is referred to as a class interval. In most cases, class ranges in a given distribution are the same width, however this is not always the case. Because class intervals comprise all elements, they should be exhaustive. The breadth of the class intervals does not have to be equal.
