What is Graphing Statistics explain ?

The number of times that an event occurs is called its frequency. One of the ways that you can compare or display different frequencies is to use a frequency table.

Usually, a frequency table is made up of two columns, the first displaying the event and the other displaying the frequency of that event.

The frequency table below describes a coin tossed 9 times, coming up heads 5 times and coming up tails 4 times:

Coin Toss

Frequency

heads

5

tails

4


Example : Create a frequency table for the following set: Create a frequency table for the following set of numbers:
{22, 14, 17, 15, 15, 12, 22, 17, 14, 17, 8, 22, 9, 17}

Step 1: What is the event?

The appearance of each number is the event.

Step 2: Find the frequency of each event (that is, count how many times each number appears).

17 appears 4 times
22
22 appears 3 times
{14 and 15} appear 2 times each

{12, 8, and 9} appear 1 time each

Step 3: Record the data into a frequency table.

Event

Note: The sum of all the frequencies must equal the total amount of numbers listed! In this case the sum is 14. The sum of all the frequencies must equal the total amount of numbers listed! In this case the sum is 14.

(4 + 3 + 2 + 2 + 1 + 1 + 1) = 14
