The marks (out of 100) obtained by a group of students in a science test are 85, 76, 90, 85, 39, 48, 56, 95, 81, and 75. Find the:

Range of the marks obtained.

Dear Student

First we have to arrange the marks obtained by a group of students in a science test in an ascending order,
= 39, 48, 56, 75, 76, 81, 85, 85, 90, 95
We know that, Range = Highest marks–Lowest marks
= 95–39
= 56

​​Thanks
