What is a Random Variable?
3. Slide

A random variable is a variable whose value is determined by chance or probability. Random variables are used to quantify the outcomes of a random experiment or process. It is important to understand the concept of random variables and their properties in order to properly analyze probability distributions.
Understanding Random Variables

Random Variable: A random variable is an entity that takes on different values randomly. It is a measure of some outcome of a random phenomenon. Probability Distribution: A probability distribution is a mathematical function that describes the probability of a random variable taking on different values. Expected Value: The expected value of a random variable is the average value that the variable is expected to take on when the experiment or process is repeated multiple times.

Random variables can be used to model a variety of real-world phenomena, such as stock market fluctuations and weather patterns. The probability function of a random variable is a function that gives the probability of each possible value for the random variable. Random variables can be continuous (like temperature) or discrete (like the number of heads from flipping a coin).

Question: You are a student studying random variables. You need to explain to your classmate what a random variable is in a way that they can understand. How would you do it? Clues: • A random variable is a variable that takes on a set of possible different values. • It is used in statistics to measure outcomes of an experiment. • It has a probability distribution that describes how likely each of its values will occur. In pairs: Select and solve one of the tasks: A. Work together in pairs to come up with a drawing that explains what a random variable is. B. Write a short story to explain what a random variable is.
