The bar graph above shows the favourite colours of 20 students in a class.
How many more of them favoured blue than those who favoured green?

Answer 1

Explanation:

According to the bar graph, the frequency of blue is 5, and the frequency of green is 2. To find out how many more students favored blue than green, we subtract the frequency of green from the frequency of blue:

5 (blue) - 2 (green) = 3

Therefore, 3 more students favored blue than green.
