Question Analysis
This question involves calculating the frequency of two specific values and finding their difference.
The main focus is on comparing frequencies of individual values and performing a simple subtraction.

Key Concept Explanation
Frequency Difference: The result of subtracting the frequency of one value from the frequency of another. It quantifies how much more (or less) often one value appears compared to another.

Step-by-Step Solution
Find the frequency of 4 inches: It appears 3 times in the dataset.
Find the frequency of 2 inches: It appears 1 time in the dataset.
Calculate the difference: 3 - 1 = 2.
