Question

what is the average of all data points in a data set?
○ the mean
○ the median
○ the mode
○ the range

Explanation:

To determine the correct answer, we analyze each option:

• The mean is calculated as the sum of all data points divided by the number of data points, which is the definition of the average of a data set.
• The median is the middle value (or average of two middle values) when data is ordered, not the average.
• The mode is the most frequently occurring value, not the average.
• The range is the difference between the maximum and minimum values, not the average.

Answer:

A. the mean
