What is the term for the numerical average, calculated by adding numbers and dividing by the total count?

Mode
Median
Mean
Range

The correct answer is: Mean

The term for the numerical average, calculated by adding numbers and then dividing by the total count, is referred to as the mean. This statistical calculation provides a measure of central tendency, representing the central point of a data set. To find the mean, you sum all the values in the dataset and then divide that sum by the number of values. This process helps to understand the overall distribution of the data. In contrast, the mode represents the number that appears most frequently in a dataset, while the median is the middle number when the data is arranged in order. The range, on the other hand, measures the difference between the highest and lowest values. Each of these terms plays a different role in statistics, with the mean being especially important for summarizing data with a single value.
