Measures of Central Tendency

Description

This example illustrates the calculation of the mean for an unfair six-sided die where the number 5 has a significantly higher probability (3/6) than other numbers. The mean is calculated using the same method as previous examples, resulting in 4.5.

This collection of examples on measures of central tendency, focusing on the mean of probability distributions, helps students understand how to calculate and interpret expected values in various scenarios. By presenting different probability distributions, students can observe how changes in probabilities affect the mean and gain insight into the concept of expected value in random events.

Providing multiple worked-out examples is crucial for students to develop a comprehensive understanding of this concept. Each example introduces a new variation in probability distribution, allowing students to apply the same calculation method to different scenarios. This repetition helps reinforce their understanding and improves their ability to solve similar problems independently.

Teacher's Script: In this example, we have an unfair die where the number 5 is much more likely to occur than other numbers. How do you think this will affect our mean? Let's work through the calculation together. Notice how the high probability of a larger number pulls our mean upward. Can you think of real-world situations where we might encounter a similar probability distribution?
