Absolute Frequency and Relative Frequency

Probability and Statistics Absolute Frequency and Relative Frequency

🎬 Video Tutorial

(0:01) Absolute Frequency: The actual count of each category in a dataset. For example, if 12 students take the bus, the absolute frequency for “bus” is 12.
(0:50) Relative Frequency: The proportion of a category, found by dividing the absolute frequency by the total. It can be expressed as a fraction, decimal, or percentage.
Using Relative Frequency to Find Absolute Values: Multiply the relative frequency by the total count to find the absolute frequency.
(1:37) Checking Total Frequencies: Always verify that the sum of all relative frequencies is 1 (or 100%) and the sum of absolute frequencies matches the total count.
