Revise: Displaying Quantitative DataA frequency table organises how often results occur. A bar chart compares separate categories or scores. A histogram shows the distribution of continuous measurements grouped into intervals.
The number of times a value or category occurs in a dataset.
Distinguish a score from its frequency: a score of 3 occurring twice means two observations, not six participants.
Check what the vertical axis represents: frequency, a score or a mean. A taller bar does not always mean more participants.
Support interpretations with values read from the display, and check that table frequencies add up to the total number of observations.
