Creating a Grouped Frequency Table

The video tutorial explains how to create a grouped frequency table using temperature data recorded by Kathy. It begins by identifying the highest and lowest temperatures, then discusses creating groups of data values, typically in multiples of five, to simplify the process. The tutorial demonstrates calculating the frequency of temperatures within each group and concludes by highlighting the importance of grouping to manage table size effectively.

What is the range of temperatures recorded by Kathy?

• 42 degrees Fahrenheit

• 31 degrees Fahrenheit

• 73 degrees Fahrenheit

• 50 degrees Fahrenheit

How many groups would there be if each group included only two values?

• 10 groups

• 15 groups

• 5 groups

• 21 groups

What is the first group range when using groups of five values?

• 30 to 34

• 35 to 39

• 50 to 54

• 40 to 44

How many temperatures fall within the range of 40 to 44?

• 5 temperatures

• 3 temperatures

• 2 temperatures

• 4 temperatures

What would be the consequence of not using grouped ranges in a frequency table?

• The table would have fewer entries

• The table would be very large

• The table would be more accurate

• The table would be easier to read
