What is the Mean?
The mean is a measure of central tendency that represents the average value of a dataset. There are several types of means: arithmetic mean (sum divided by count), geometric mean (nth root of the product), harmonic mean (reciprocal of arithmetic mean of reciprocals), and weighted mean (accounts for different importance of values).

Frequently Asked Questions
Use geometric mean when dealing with multiplicative relationships, such as growth rates, compound interest, or ratios. For example, if an investment grows 10% one year and 20% the next, geometric mean gives the true average growth rate, while arithmetic mean would overestimate it.
