Study Notes
Understanding Frequency
- Frequency is the number of times a value occurs in a set of data.
- It can be represented in a frequency table, which shows how often an event happened.
Victor's Gumball Machine Example
- Victor tried to get a red gumball from a machine 9 times.
- He got the following results: 2 green, 1 blue, 1 yellow, 3 orange, and 1 red.
- By looking at the frequency table, Victor realized he had a low chance of getting a red gumball again (1 out of 9).
Creating a Frequency Table
- Start by listing the values or categories (e.g., gumball colors).
- Make tally marks to keep track of the number of occurrences for each value.
- Count the tally marks and write down the total frequency for each value.
Dice Rolling Example
- Rolling a die can result in numbers 1-6.
- Paul rolled a die 10 times and got the following results: 2 sixes, 3 threes, 1 two, 1 one, 2 fives, and 1 four.
- Paul created a frequency table to show the results.
Your Turn
- You can create a frequency table for any set of data you want to analyze.
- Examples include the frequency of letters in your name, colors of shirts in your closet, or types of books you own.
