What is the mean of a data set?

The highest value
The middle value
The average of the numbers
The most frequent value

The correct answer is: The average of the numbers

The mean of a data set is defined as the average of all the numbers within that set. To calculate the mean, you sum all the values and then divide that total by the number of values. This measure provides a central tendency of the data, allowing for a comparative analysis of different data sets. In contrast, the highest value refers to the maximum in the data set, while the middle value pertains to the median, which is the value that separates the higher half from the lower half when the data is sorted. The most frequent value, known as the mode, indicates which number appears most often in the set. These other measures of central tendency serve different purposes in statistical analysis.
