the median salary of the data​

Answer 1

Explanation:

We can think of median as a mid value for the given data...

The number of students were 1000 which is an even number ... So we will take n/2 and n/2 + 1

i.e. 500 and 501 which should be included in the cumulative frequency of median class

median class is 25-30 and its c.f. is 663 which includes 500 and 501

Lower limit of this median class is 25
