Q48 of 91 Page 72

State whether the statements are True or False.

The range of the data 2, –5, 4, 3, 7, 6 would change if 2 was subtracted from each value in the data.

False

Range for the original data = 7-(-5) = 12.


The new data would be 2-2, -5-2, 4-2, 3-2, 7-2, 6-2.


i.e., 0, -7, 2, 1, 5, 4.


The new range would be 5-(-7) = 12


So the range will not change.
