Exploring Mean, Median, Mode, and Range

This video tutorial reviews the concepts of mean, median, mode, and range. It explains how to calculate each measure from a dataset, providing definitions and step-by-step instructions. The mean is calculated by averaging the numbers, the median is the middle value when numbers are ordered, the mode is the most frequently occurring number, and the range is the difference between the highest and lowest numbers. The video includes examples to illustrate these calculations.

What is the first step in calculating the median of a set of numbers?

• Add all the numbers together

• Arrange the numbers in ascending or descending order

• Find the number that appears most frequently

• Subtract the smallest number from the largest
