Question

In preparing a pictograph for the data: Farming (60), Private Job (20), Government Job (30), and Other (40), which scale would be most efficient?

Options

• 1 picture = 5 students

• 1 picture = 10 students

• 1 picture = 15 students

• 1 picture = 20 students

Answer 1

1 picture = 10 students

Explanation:

All values (60, 20, 30, 40) are divisible by 10, which creates a clean representation without excessive symbols or too many half-symbols. Scale of 10 is also easy to interpret.
