This video tutorial by Mr. J explains how to create a frequency table, specifically a grouped frequency distribution table. It covers the importance of frequency tables in organizing and displaying data, and demonstrates how to find the range of a data set. The tutorial guides viewers through determining the number of classes and class width, and provides a step-by-step process for filling in the table with data. The video concludes with a review of the completed frequency table, emphasizing its utility in representing data effectively.

What is the primary purpose of a frequency table?

• To calculate averages

• To organize and display data

• To solve equations

• To predict future trends

Why is it not ideal to list each individual number in a frequency table with a large range?

• It makes the table too short

• It does not affect the table

• It results in a table with many zero frequencies

• It is too complex to calculate
