A frequency table is a table that records how often each value or category occurs in a data set, organizing raw data into a clear summary with categories in one column and their counts (frequencies) in another. Frequency tables are the foundation for most other statistical displays.
Definition
A frequency table is a table that records how often each value or category occurs in a data set, organizing raw data into a clear summary with categories in one column and their counts (frequencies) in another.
💡 Intuition
A frequency table is an organized list that answers 'how many?' for each category. Instead of a messy list of responses, you get a clean summary: Pizza-12, Tacos-8, Burgers-5.
🎯 Core Idea
A frequency table converts a raw list into a compact summary showing how many times each category or value appears.
Example
🌟 Why It Matters
Frequency tables are the foundation for most other statistical displays. They organize raw data into usable summaries.
💭 Hint When Stuck
First, list all possible values or categories in the left column. Then go through each data point and add a tally mark next to its category. Finally, count the tally marks and write the total frequency for each category in the right column.

🚧 Common Stuck Point
Students sometimes leave out categories with zero frequency, which can hide gaps and make totals incorrect.
⚠️ Common Mistakes
- Missing categories
- Counting errors
- Not including all values from original data
