What is the range of the set of data {2, 4, 6, 8}?

To find the range of a set of data, you need to subtract the smallest value in the set from the largest value. In the given set {2, 4, 6, 8}, the smallest number is 2 and the largest number is 8.

Calculating the range involves the following steps:

1. Identify the smallest number: 2

2. Identify the largest number: 8

3. Subtract the smallest number from the largest number: 8 - 2 = 6

Thus, the range of this data set is 6. This value represents the spread of the data, indicating how much variation there is from the lowest to the highest value. Therefore, the correct answer reflects the calculated range accurately.
