The average of a distribution, calculated as the summation of all data points (x) divided by the number of observations, is referred to as the mean.
The mean is a fundamental concept in statistics, representing a central value of a data set. To calculate the mean, you add together all the individual values (x) in your data set and then divide that sum by the total number of observations. This gives you a single value that summarizes the data, providing insight into its overall tendency. The mean can be influenced by extremely high or low values, which makes it important to consider the context of the data when interpreting the mean.
