2 goals — that stack has 4 dots, the tallest.
Level 3 · Challenge
7 Same dot plot. How many goals were scored altogether across all the games?

0 + 3 + 8 + 6 + 4 = 21 goals.

Show worked solution
2 + 1 = 3 games.
9 A column graph starts its frequency scale at 6 rather than 0. What does this do to the columns?
Show worked solution
It exaggerates the differences, which makes the graph misleading even though the numbers are correct.
