What does "mean" refer to in statistics?

• A. The most frequently occurring value
• B. The largest value in a data set
• C. The average of a data set
• D. The midpoint of a data set

Answer: (C)

In statistics, "mean" specifically refers to the average of a data set. To calculate the mean, you sum all the values in the dataset and then divide that total by the number of values. This measure provides a central value that represents the data set as a whole, helping to convey a sense of the overall distribution of values. For example, if you have the numbers 2, 4, and 6, the mean would be calculated as (2 + 4 + 6) / 3, which totals 12 and when divided by 3, results in a mean of 4. This average gives you a good understanding of where most of the data points lie in relation to one another. The other choices represent different statistical concepts: the most frequently occurring value refers to the mode, the largest value is known as the maximum, and the midpoint of a data set pertains to the median. Each of these measures provides different insights into the data, but only the mean represents the average.
