Calculating and Comparing Mean, Median, and Mode

Miacademy & MiaPrep Learning Channel

This educational video provides a comprehensive introduction to the three primary measures of central tendency: mean, median, and mode. Through clear definitions and real-world examples, it explains how statisticians and everyday people use these tools to find the "center" or typical value of a dataset. The video uses a relatable running example of tracking daily screen time to demonstrate how to calculate each measure and compares how they behave differently, particularly when outliers are present. The lesson goes beyond simple calculation by visualizing data using histograms and box-and-whisker plots. It explores complex concepts such as data distribution, quartiles, and the impact of skewed data on the mean versus the median. The video also distinguishes between numerical and categorical data, explaining why mode is unique in its application to non-numerical preferences. For educators, this resource serves as an excellent core lesson for a statistics unit in middle or high school math. It directly addresses the critical critical thinking skill of choosing the *right* measure to represent data, rather than just calculating all three blindly. The included pauses for calculation and reflection make it an interactive tool for flipped classrooms or guided whole-group instruction.
