Making a Grouped Frequency TableA grouped frequency table is a great way to present a lot of data. Imagine a teacher collected the test scores of their mathematics class:
Depending on each student's test score, the teacher will assign a grade:
How to Make a Grouped Frequency TableMaking a grouped frequency table is easy.
QuestionConstruct a grouped frequency table for the numbers below.
Construct a table with three columns:
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.
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.
For each row, count the tally marks. Write the number of tally marks in the Frequency column.
