Lesson: 21: Statistics
Topic: Frequency and Cumulative Frequency
Domain: Statistics

A frequency table trades individual detail for a shape you can see. Tally through the data once, in order, and check the frequencies add to the total.

Study Tip

Classes must not overlap and must not leave gaps. Every possible value has to fit in exactly one class, and checking that takes five seconds.
