When considering average scores, which of the following correctly describes the mean?

The mean is defined as the sum of all the values in a set divided by the number of values in that set. This calculation gives a single value that represents the average of the data. For example, if you have a set of test scores, you would add all the scores together and then divide that total by the number of scores to find the mean.

This method captures the overall performance by considering every score in the dataset, making it a useful measure of central tendency. In contrast, the highest score, the most frequent score, and the lowest score do not provide an average but rather specific data points that might not reflect the overall performance of the group or set being analyzed. By focusing on the total sum and the count of entries, the mean provides a balanced assessment of the data.
