Calculating averages is a fundamental task in data analysis, and MATLAB provides robust tools to perform this operation efficiently. In this guide, we will explore various methods to calculate different types of averages in MATLAB, including arithmetic mean, weighted average, and more.

Arithmetic Mean

The arithmetic mean is the most common type of average. MATLAB makes it straightforward to compute this using the mean function.
