Understanding Range from a Frequency Table

In this video, Mr. J explains how to find the range from a frequency table. The range is the difference between the highest and lowest values in a dataset, indicating how spread out the data is. Using a frequency table of bike ride distances, Mr. J demonstrates the calculation by subtracting the shortest distance from the longest distance, resulting in a range of 8 miles. The video concludes with a summary of the process.

What does the range of a dataset tell us?

• How spread out the data is

• The sum of all data points

• The average value of the data

• The median value of the data

Why is it important to label the range with units?

• To ensure clarity and understanding of the data

• To make it look more professional

• To confuse the reader

• To add more information than necessary
