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

How do you calculate the range from a frequency table?

• Add the highest and lowest values

• Multiply the highest and lowest values

• Subtract the lowest value from the highest value

• Divide the highest value by the lowest value

In the example, what is the highest value recorded for bike ride distances?

• 13 miles

• 8 miles

• 10 miles

• 5 miles

What is the lowest value recorded in the bike ride distance example?

• 7 miles

• 5 miles

• 3 miles

• 9 miles

What is the calculated range for the bike ride distances?

• 13 miles

• 8 miles

• 10 miles

• 5 miles

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

What is the final step in finding the range from a frequency table?

• Subtract the lowest value from the highest value

• Find the average of the values

• Multiply the highest and lowest values

• Add all the values together
