Understanding Relative Frequency Distribution

This video tutorial explains how to create a relative frequency distribution table. It begins by introducing the concept and providing a data set. The tutorial then guides viewers through creating a frequency table, calculating relative frequencies, and verifying the results. The video concludes with a summary and a recommendation to watch the next video on cumulative relative frequency.

What is the first step in creating a relative frequency distribution table?

• Create a cumulative frequency table

• Determine the highest value

• Calculate the total frequency

• List the data set values

How do you calculate the relative frequency of a value?

• Divide the value by the total number of values

• Multiply the frequency by the total frequency

• Divide the frequency by the total frequency

• Subtract the frequency from the total frequency

Which value has a relative frequency of 0.25?

• 5

• 3

• 2

• 8

What is the purpose of verifying the sum of relative frequencies?

• To ensure the data set is complete

• To confirm the calculations are correct

• To identify the most frequent value

• To determine the range of the data set

What should you do if the sum of relative frequencies is not 1.0?

• Ignore the discrepancy

• Add more data to the set

• Check for calculation errors

• Recalculate the total frequency
