Consider the marks obtained by 10 students in a mathematics test as given below: 55 36 95 73 60 42 25 78 75 62 The data in this form is called raw data. By looking at it in this form, can you find the highest and the lowest marks?

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`
