Frequency Distribution
A precise tool.
What is the Frequency Distribution & How does it work?
A frequency distribution summarizes how often each value or range of values occurs within a data set, providing a clear picture of the data’s shape and central tendency.
To construct a frequency distribution, the data range is divided into a specified number of equal-width classes. Each observation is then placed into the appropriate class, and the count of observations per class (the absolute frequency) is recorded.
Relative frequencies are obtained by dividing each class’s absolute frequency by the total number of observations, yielding proportions that sum to one. This facilitates comparison across data sets of different sizes.
f_i = frac{n_i}{N}
f_i = relative frequency of class i

Frequently Asked Questions
What is a frequency distribution?
A frequency distribution summarizes how often each value or range of values occurs within a data set.
How do I construct a frequency distribution?
Divide the data range into equal-width classes, then count the number of observations in each class.
What is absolute frequency?
Absolute frequency is the count of observations that fall within a specific class.
How do I calculate relative frequencies?
Divide each class's absolute frequency by the total number of observations.
Why use a frequency distribution calculator?
It helps visualize data patterns and central tendencies easily.
Can I use this calculator for continuous data?
Yes, you can define class intervals to handle continuous data effectively.
What does the shape of a frequency distribution tell me?
It indicates whether the data is symmetric, skewed, or has multiple peaks.
