Probability and Sampling Distributions

Definition

Probability and sampling distributions involve the study of the likelihood of events occurring and how data is distributed. It explores the chances of different outcomes happening and how those outcomes are spread out.

Analogy

Imagine you're at a carnival playing a game where you have to throw darts at balloons. The probability is like knowing your chances of hitting a balloon based on your skill level. The sampling distribution is like seeing how many times you hit the target in multiple rounds, creating a distribution of your results.

Random Variable: A random variable represents an uncertain quantity or outcome in a statistical experiment.

Normal Distribution: A normal distribution is a bell-shaped curve that represents the pattern of data clustering around the mean.

Central Limit Theorem: The central limit theorem states that as sample size increases, the sampling distribution approaches a normal distribution regardless of the shape of the population distribution.
