Collect the data by writing it on a piece of paper. For example, let's say we have data that consists of following 25 numbers: 1, 3, 5, 3, 7, 5, 8, 9, 2, 6, 6, 13, 20, 21, 34, 43, 10, 23, 5, 10, 5, 3, 5, 6 and 8.
Rearrange the data so that it starts with the smallest number and ends with the highest number. In this example, this data will be rearranged as follows: 1, 2, 3, 3, 3, 5, 5, 5, 5, 5, 6, 6, 6, 7, 8, 8, 9, 10, 10, 13, 20, 21, 23, 34 and 43.
Create two columns. Title first column as "X." The first column represents all possible values of your data. Title second column as "Frequency." The second column represents "how frequent" each value of the first column occurred.
Look at the first value in Step 2. As you can see the first value is "1"; write "1" under "X" column. Now count how many times the value "1" occurred. You will notice the value "1" occurred only one time. Write "1" under "Frequency" column. Similarly, look at the second value, which is "2," in Step 2. Write "2" right under 1 of "X" column. Again count how many times the value "2" occurred. Since "2" also occurred only once, write "1" under "1" of "Frequency" column.
Repeat Step 4 for all 25 values of your data set. Once you complete filling out all possible values in the "X" column and their occurrence in the "Frequency" column, your frequency distribution is complete.
Your Frequency Distribution will look like this:
X Frequency
1 1
2 1
3 3
5 5
6 3
7 1
8 2
9 1
10 2
13 1
20 1
21 1
23 1
34 1
43 1
