Mean-ungrouped Distribution by Deviation method|Measures of Central Tendency|TG 9|Math|Khan Academy

Описание: In this video, we explore how to calculate the mean using the deviation method, and why it can be more efficient than the direct method—especially when dealing with large or grouped data. By introducing the concept of assumed mean and simplifying calculations through deviations, we show how this approach reduces computational load and reveals patterns more clearly. Through step-by-step examples, you'll learn how to apply the method, interpret deviations, and compare results with the direct method to understand its advantages.
