Question

58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57

If a value of 80.8° is added to the data, how does the range change?

Answer 1

Step 1: find the original data set is 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105.

Step 2: find the range

105 - 57 = 48

The range for the original data set is 48.



The new data set is adding 80.8

Step 1: find the new data set.

57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105

Step 2: find the range

105 - 57 = 48.

The range is still the same for the original and new data set.

Answer 2

The original data set would be:

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

So to find the range you would do:

105 - 57 which equals 48.

So the range for the original data set would be 48.

The new data set adding 80.8:

57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105

So to find the range for the new data set you would do:

105 - 57 which would still equal 48.

So the range for the new data set would be 48.

The range for the original and new data set stayed the same.
