Question

In a distribution, the classes are as follows:
(i) 10 – 19, 20 – 29, 30 – 39
(ii) 3.5 – 7.5, 8 – 12, 12.5 – 16.5
Make these classes continuous. Also find the class size.

answer only if u know :)​

Answer 1

Answer:

(i) 10 - 19, 20 - 29, 30 - 39

continuous distribution is as follows

9.5 - 19.5, 19.5 - 29.5, 29.5 - 39.5

size of class = 19.5 - 9.5 = 10

(ii) 3.5 - 7.5, 8 - 12, 12.5 - 16.5

continuous distribution is as follows

3.25 - 7.75, 7.75 - 12.25, 12.25 - 16.75

size of class = 7.75 - 3.25 = 4.5
