Question

For the data set, the mean is 3.26 and the range is 1.5. The data is transformed by subtracting 0.5 from each data value. What are the mean and range of the new data set?

Answer 1

Answer:

Mean of the new data set = 2.76

range = 1.5

Step-by-step explanation:

For the data set, the mean is 3.26 and the range is 1.5.

The data is transformed by subtracting 0.5 from each data value.

Mean is also average of the data set. As a general rule the mean will be changed by adding or subtracting a constant to each value. However the range will remain the same.

The mean would be 3.26 - 0.5 = 2.76

There is no change in the range, so the range would be same = 1.5

Answer 2

The mean of the new data set is 2.76, and the range of the new data set is 1.5.
