Answer 1

Answer:

Step-by-step explanation:

By looking at raw data, we can find the highest and lowest marks.

But, if we arrange data in ascending or descending form, then it will be much easier to find the highest and lowest marks.

Given data in ascending order,

25,36,42,55,60,62,73,75,78,95

So, from this, we can easily find,

Lowest marks =25

Highest marks =95
