Question

The following bar graph shows the favourite colours of 20 students of a class.

What can be inferred from the graph?

• A. Red is the favourite colour of the least students.
• B. Blue is the favourite colour of most students.
• C. Pink and green are equally liked.
• D. Orange is the third most popular colour.

Answer 1

The correct option is B Blue is the favourite colour of most students.

From the graph, it can be observed that:
Frequency of Blue = 6
Frequency of Orange=5
Frequency of Yellow=3
Frequency of Pink=3
Frequency of Red=2
Frequency of Green=1

Therefore, blue is most favoured colour and orange is second most favoured colour. Thus, option A is correct and C is incorrect. The least favoured colour is green so option B is incorrect. Also the frequency of green and pink are different. So option D is also incorrect.
