The idea of a random variable can be surprisingly difficult. In this video we help you learn what a random variable is, and the difference between discrete and continuous random variables. • 0:00 Introduction • 1:13 X is defined as the number of ice creams a customer orders • 1:30 Historic data is used to estimate the probability of each number of ice creams • 1:50 The distribution is graphed, find P(X=1) etc • 3:07 Examples of discrete random variables, not random variables, and continuous random variables. • 4:13 Quiz to check your understanding • This video leads on to other videos about random variables and distributions: • Discrete random variables: • Discrete Random Variables: Distributi... • Probability distribution models: • Probability Distribution Models inclu... • The normal distribution: • Understanding the normal distribution... • The binomial distribution: • Understanding the Binomial Probabilit... • See https://creativemaths.net/videos/ for all of Dr Nic's videos organised by topic. • #DrNicStats #Statistics #Probability
