14 Standardising a Variable

About this lesson
This video explains the concept of standardization, a crucial process for transforming any random variable into one with a mean of 0 and a variance of 1. It details the two key steps: first, subtracting the population mean to center the distribution, and then dividing by the standard deviation. Learn how these transformations precisely affect the mean and variance, with a clear proof for why the variance becomes one. Understand how to standardize any random variable to achieve a distribution with a mean of 0 and a variance of 1. Subscribe to @AxiomTutoringCourses for more insightful videos.
