In a data interpretation scenario, the sum of 12 data points is 240. What is the mean value of the data set?

Explanation:
The mean (average) is found by dividing the total sum by how many data points there are. Here, 12 data points sum to 240, so the mean is 240 ÷ 12 = 20. This matches the given total, and the other values would require a different total for 12 points (e.g., 18 would imply 216, 24 would imply 288, 22 would imply 264), which isn’t the case.
