Problem Solving & Reasoning
Solve these multi-step problems involving comparing groups with dual bar charts.
1.

[2 marks]3.
Two dual bar charts show different data about student preferences. How can you determine which group prefers a category more?
[3 marks]4.
A dual bar chart indicates that 50 students favor Option X and 20 favor Option Y in Group 1. In Group 2, 45 favor Option X and 35 favor Option Y. Which option is more popular overall?
[3 marks]D
Real-world Applications
Apply your understanding to real-world scenarios involving comparing groups with dual bar charts.
1.
A dual bar chart shows that in a school survey, 55 students like Chocolate, while 40 like Vanilla. Which flavor is preferred more, and by how many students?

[3 marks]2.
Given a dual bar chart showing that 70 students prefer online learning while 30 prefer traditional classrooms, what conclusions can be drawn about student preferences?
[3 marks]F
Mixed Review
Answer a variety of questions to review key concepts.
1.
