# The range of the data 3, 7, 1, –2, 2, 6, –3, –5 would change if 8 was added to each value in the data. State whether the statement is true or false.

**Solution:**

Given, The __range__ of the data 3, 7, 1, –2, 2, 6, –3, –5 would change if 8 was added to each value in the data.

We have to determine if the given statement is true or false.

We know that the difference between the highest and lowest observations in a given __data__ is called its Range.

Case(i) Arranging the data in __ascending order__, we get

-5, -3, -2, 1, 2, 3, 6, 7

Highest observation = 7

Lowest observation = -5

Range = 7 - (-5)

= 7 + 5

= 12

Case(ii) On subtracting 2 from each value in the dat, we get

(3 + 8), (7 + 8), (1 + 8), (-2 + 8), (2 + 8), (6 + 8), (-3 + 8), (-5 + 8)

The data becomes 11, 15, 9, 6, 10, 14, 5, 3

Arranging the data in ascending order, we get

3, 5, 6, 9, 10, 11, 14, 15

Highest observation = 15

Lowest observation = 3

Range = 15 - 3

= 12

Therefore, the range remains the same in both the cases.
