Question

In a frequency distribution, the mid value of a class interval is 26. if the class size is 10. calculate the upper and lower limits of the class respectively.

Answer 1

class size mid value = 10/2= 5
Lower Limit= mid value of a class interval - 5 = 26-5 = 21
Upper Limit = mid value of a class interval + 5 = 26+5 = 31
