This lecture explains the concept of variance for a random variable, starting with the expectation value or mean denoted by the Greek letter mu. It delves into the computation of variance, measuring the distance of values from the mean, and introduces the formula for variance. The lecture also covers calculation rules for variance, including the impact of shifting a random variable by a constant and the variance of two independent random variables.
