Скачать или смотреть Mean of individual, discrete and continuous series data [ALL SERIES] using simple formulas

The mean is a measure of central tendency that indicates the average value of the dataset. In this video, I explain how to compute the mean of individual, discrete, and continuous series data using real scenarios.
Individual series: Add all values and divide by the total number.
Discrete series: Multiply each value by its frequency (how many times it appears) and sum those products. Then divide by the total number of observations.
Continuous (grouped): Estimate by calculating a midpoint for each value range (class), multiply by its frequency, sum those products, and divide by the total observations.
In short, for individual and often discrete data, simply add and divide. For continuous data (grouped), estimate the mean using midpoints and frequencies.
