Making a grouped frequency table is easy.

## Question

Construct a grouped frequency table for the numbers below. # 1

Construct a table with three columns: # 2

In the Score column, write the groups of numbers. In our example, we will use the group of test scores assigned to the different grades. # 3

Go through the set of numbers in the Question. For each number, see which of the group of numbers it belongs in. Cross it out and put a tally mark in the Tally column, in the row for that group of numbers.
• The first number is 2. It belongs in the 1 - 5 group. Cross it out and put a tally mark in the Tally column in the 1 - 5 row. • The second number is 10. Cross it out and put a tally mark in the Tally column in the 10 row. • Continue until all numbers have been crossed out and had tally marks placed in the Tally column. # 4

For each row, count the tally marks. Write the number of tally marks in the Frequency column.
