Question

In a frequency distribution,the mid value of a class is 10 and the width of the class is 6. Find the lower limit of class.

Answer 1

The class interval is 7-13. So the lower limit is 7.

Answer 2

Answer:

Mid value = 10 cm

Width = 6

Lower Limit = mid value of class - width/2

                                                           

                 = 10 - 6/2

                           

                  = 10 - 3

                  = 7
