Content Analysis

Probability Distributions

A probability distribution is a mathematical function that describes the likelihood of different outcomes in a random experiment. The lesson introduces students to various types of probability distributions, including the binomial distribution, the normal distribution, and the Poisson distribution.

Expected Value

Expected value, also known as mean, is a measure of the central tendency of a probability distribution. The lesson explains how to calculate expected value and its significance in decision-making.

Variance

Variance is a measure of the spread or dispersion of a probability distribution. The lesson covers the formula for calculating variance and its role in understanding the variability of data.
