Frequency Table

This Frequency Table Calculator helps you analyze how often values occur in your dataset by organizing them into a structured table. It calculates the frequency (count) of each unique value, helping you understand the distribution and patterns in your data. For example, you can analyze student grades, product categories, or any other data to see how many times each value appears.

What is a Frequency Table?

A frequency table is a statistical tool that organizes data by displaying how often each distinct value occurs in a dataset. It provides a structured way to summarize data distribution through counts and percentages.

Absolute Frequency

The actual count of how many times each value appears in the dataset.

Raw counts
Direct observations
Actual frequencies

Relative Frequency

The proportion or percentage of each value in relation to the total.

Proportions
Percentages
Ratios

Key Components

Essential Elements:

Categories or values
Frequency counts
Relative frequencies
Cumulative frequencies

Optional Elements:

Class intervals
Percentage distribution
Summary statistics
Visual representations

Academic Example: Final Exam Scores Distribution

Distribution of final exam scores for 100 students in a statistics course.

Score Distribution

Score Range	Grade	Frequency	Percentage	Cumulative %
90-100	A	15	15.0%	15.0%
80-89	B	25	25.0%	40.0%
70-79	C	35	35.0%	75.0%
60-69	D	20	20.0%	95.0%
Below 60	F	5	5.0%	100.0%

Grade Distribution

Key Insights:

Mode: Grade C (Most common grade)
40% of students received grades B or higher
Only 5% of students failed the exam
The distribution shows a roughly normal curve

This frequency table helps instructors understand the overall class performance, identify areas for improvement, and compare with expected grade distributions.
