Chapter 4: Probability distributions

‘Stats in the Real World’ Weblinks are provided from the book’s feature to enhance your learning and practical experience.

Web link 1: YouTube channel Numberphile gives an example of how probability doesn’t always work the way you intuitively think it should, which could lose you money on a game show

Web link 2: A demonstration from the National HE STEM Programme shows how normal distributions occur naturally given randomness alone using a real-life Galton Board
