What is the average of all the scores in a dataset known as?

The average of all the scores in a dataset is referred to as the mean. To calculate the mean, you sum all the values in the dataset and then divide that total by the number of values (or scores) present. This measure gives a central value that represents the entire set of data, making it useful for understanding the overall trend or typical score in a dataset.

The median, while another measure of central tendency, specifically refers to the middle value when all scores are arranged in order, and may not accurately reflect the average of the dataset when outliers are present. The mode identifies the most frequently occurring score in the dataset, while the range indicates the difference between the highest and lowest scores, neither of which represents the average of the scores. Thus, mean is the appropriate term for the average score in a dataset.
