Consider this data collected from a survey of a colony. Favourite Sport: Cricket, Basket Ball, Swimming, Hockey, Athletics. Watching: 1240, 470, 510, 430, 250. Participating: 620, 320, 320, 250, 105. Choose an appropriate scale and draw a double-bar graph. Write down your observations.
Draw a double bar graph with sports on the x-axis and number of people on the y-axis. Use scale 1 unit = 200 or 250 people. Observations: Cricket is the most popular for both watching and participating. Athletics has the lowest participation. More people watch than participate in all sports. The gap between watching and participating is largest for Cricket.
Explanation
Students should choose a scale that allows all values to fit on the graph (maximum is 1240, so scale of 1 unit = 200 works well). The double bar graph shows two bars per sport - one for watching and one for participating. Key observations include the popularity ranking and the difference between watching and participating numbers.
Solution Steps
Step 1: Identify maximum value: 1240 (Cricket watching)
Step 2: Choose scale: 1 unit = 200 people (y-axis goes to 1400)
Step 3: Draw x-axis with 5 sports
Step 4: Draw y-axis with scale markings
Step 5: Draw paired bars for each sport with different colors
Step 6: Write observations about popularity and watching vs participating patterns
