Question Analysis
This question involves the concept of range, which is a simple measure of dispersion in statistics.
The main focus is on calculating the difference between the maximum and minimum values in a data set.

Key Concept Explanation
The range of a data set is calculated as the difference between the maximum value and the minimum value.
It gives a quick indication of how spread out the data is.

Step-by-Step Solution
Identify the maximum value in the data set {10, 12, 14, 16, 18}, which is 18.
Identify the minimum value, which is 10.
Calculate the range: Range = Maximum value - Minimum value = 1...
