Question

How to calculate mean median mode class interval data?

Answer 1

Answer:

mean-

sum of the total no. of observations divided by the no. of observations

median-

odd no.-

eg-5,7,9,12,18

no. of observations- 5

no. of observations plus 1 to make it even= 5 + 1=6

                                                                       6/2 = 3

                                                    therefore the 3rd value is the the median

that is 9!

mean-

the frequency of a no.
