Question

6. Find the class boundaries for the following class intervals



Class interval

1 – 9

10 – 19

20 – 29

30 – 39

40 – 49


​

Answer 1

10−19,20−29,30−39,...

Here the class intervals are not continuous. To make them continuous take the mean of upper limit of first class and lower limit of second class.

Mean =

2

19+20

=19.5, which gives the upper limit of first class and lower limit of second class for the continuous class intervals.
