Understanding Range, Mid-Range, and Coefficient of Range

The video tutorial explains how to calculate the range, mid-range, and coefficient of range from a given data set. It begins by identifying the lowest and highest numbers to find the range, then calculates the mid-range as the average of these numbers. Finally, it demonstrates how to compute the coefficient of range by dividing the range by the sum of the highest and lowest numbers.

What is the first step in solving the problem presented in the video?

• Calculate the average of all numbers

• Identify the lowest and highest numbers

• Find the median of the dataset

• List all numbers in ascending order
