How to teach it
Work the whole cycle: pose a question, collect the data into a table, choose a display, then interpret it (total, mode, range, differences) and report what it shows.
Worked example
How many students took part in this survey altogether?
Answer: 55
Why: 7 + 15 + 20 + 13 = 55
Common mistake
Collecting data before the question is clear, and confusing the range (spread) with the total.
