1.	The marks obtained by 17 students in a mathematics test (out of 100) are given below:90, 79, 76, 82, 65, 96, 100, 91, 82, 100, 49, 46, 64, 48, 72, 66, 88.Find the range of the above data.
Answer» Arrange the given data in ascending order 46, 48, 49, 64, 65, 66, 68, 72, 76, 79, 82, 82, 90, 91, 96, 100, 100 So from the data we know that Minimum marks = 46 and Maximum marks = 100 We know that Range of the given data = Maximum marks – Minimum marks = 100 – 46 = 54 Therefore, the range of the above data is 54.

The marks obtained by 17 students in a mathematics test (out of 100) are given below:90, 79, 76, 82, 65, 96, 100, 91, 82, 100, 49, 46, 64, 48, 72, 66, 88.Find the range of the above data.

Answer»

Arrange the given data in ascending order

46, 48, 49, 64, 65, 66, 68, 72, 76, 79, 82, 82, 90, 91, 96, 100, 100

So from the data we know that

Minimum marks = 46 and Maximum marks = 100

We know that

Range of the given data = Maximum marks – Minimum marks = 100 – 46 = 54

Therefore, the range of the above data is 54.
