Question 8 of 18intermediate🔧 ApplyDiagram4 marks

Preyashi asked her students 'If you were to get a super power to become aquatic (water-borne), aerial (air-borne), or spaceborne which one would you choose?'. The responses are shown below. Some chose none. Draw a double-bar graph comparing how both grades chose each option. Choose an appropriate scale.

Correct Answer

Students should count the frequency of each choice (aquatic, aerial, spaceborne, none) for Grade 5 and Grade 9 separately. Then draw a double bar graph with categories on the x-axis and frequency on the y-axis. Use two different colors for Grade 5 and Grade 9 bars side by side for each category. An appropriate scale would be 1 unit = 2 or 1 unit = 5 students depending on the counts.

Explanation

Grade 5 data: w(3), a(9), s(2), n(4). Grade 9 data: w(4), a(5), s(8), n(3). Students count each category, choose a scale (e.g., 1 unit = 2 students), and draw bars for each category showing both grades side by side.

Solution Steps

  1. Step 1: Count Grade 5 responses: w=3, a=9, s=2, n=4

  2. Step 2: Count Grade 9 responses: w=4, a=5, s=8, n=3

  3. Step 3: Choose scale: 1 unit = 2 students

  4. Step 4: Draw x-axis with categories: aquatic, aerial, spaceborne, none

  5. Step 5: Draw y-axis with frequency scale

  6. Step 6: Draw paired bars for each category with different colors for each grade
