What is the correct definition of the mean in mathematics?

The mean in mathematics is indeed defined as the average of a set of numbers. To calculate the mean, you sum all the values in a dataset and then divide that sum by the total number of values in the dataset. This statistical measure provides a central tendency that represents the typical value in the dataset, making it a widely used way to describe the data's overall magnitude.

Understanding the mean is important in various fields such as statistics, finance, and social sciences, as it helps to summarize and analyze data sets effectively. The mean is particularly useful for datasets that are not heavily skewed, allowing for a reliable representation of the data's central value.
