Question

For a grouped frequency distribution that contains an expected class or category frequency that is less than 5, two or more classes can be combined so that the frequency is 5 or more.

True or False?

Answer 1

Answer : True

Explanation : The "expected" count of each category has to be greater than 5, so when you have categories with expected count lesser than 5, combined that category and merge it with another category.

Example : Suppose you have category 1 with count 4 and then another category with count 3, add these two categories so total count will be 4+3= 7>5
