CAAT - Canadian Adult Achievement Interpreting Data and Graphs Questions and Answers — Questions and Answers
Question 1: The bar chart below shows the number of vehicles sold by a dealership in one week. How many more cars were sold than motorcycles and trucks combined?
- 10
- 25
- 5 (Correct answer)
- 15
Correct answer: 5
First, find the combined total of motorcycles and trucks sold. Motorcycles sold = 15. Trucks sold = 20. Combined total = 15 + 20 = 35. Next, find the number of cars sold, which is 40. Finally, calculate the difference: 40 (Cars) - 35 (Motorcycles + Trucks) = 5. Therefore, 5 more cars were sold than motorcycles and trucks combined.
Question 2: The line graph below tracks the monthly profit of a small business over six months. Between which two consecutive months was the greatest increase in profit observed?
- January to February
- March to April (Correct answer)
- April to May
- February to March
Correct answer: March to April
To find the greatest increase, calculate the difference in profit between each pair of consecutive months. Jan-Feb: $4000 - $3000 = $1000. Feb-Mar: $3500 - $4000 = -$500 (a decrease). Mar-Apr: $6000 - $3500 = $2500. Apr-May: $6500 - $6000 = $500. May-Jun: $6000 - $6500 = -$500 (a decrease). The largest increase was $2500, which occurred between March and April.
Question 3: A survey asked 200 students to name their favourite sport. The results are displayed in the pie chart below. According to the chart, how many students chose Hockey as their favourite sport?
- 35 students (Correct answer)
- 70 students
- 45 students
- 20 students
Correct answer: 35 students
The pie chart shows that Hockey was chosen by 35% of the students. To find the number of students, calculate 35% of the total number of students surveyed (200). Calculation: 0.35 * 200 = 70. However, the question asks for the number of students who chose Hockey, and the slice is labeled 35%. Let's assume the chart labels are: Basketball 25%, Soccer 40%, Hockey 35%. Wait, 25+40+35 = 100. Okay. Let's re-read. Ah, let's make the percentages more realistic for a 4-slice pie. Let's use: Basketball (25%), Soccer (40%), Hockey (15%), Baseball (20%). Total 100%. Okay, let's re-write the question based on new, clear data. New data: Soccer 40%, Basketball 25%, Baseball 20%, Hockey 15%. Total students = 200. The question is how many chose Hockey. Hockey is 15%. Calculation: 0.15 * 200 = 30 students. Let's adjust the answers. Okay, let's try another set of numbers that is easier to work with. Let's say total students = 300. Pie chart: Soccer 40%, Hockey 25%, Basketball 20%, Baseball 15%. How many chose Hockey? 25% of 300 is 0.25 * 300 = 75. This is a good, clear question. Let's finalize this one. Okay, I will re-create the explanation based on a hypothetical chart where Hockey is 25% of the total. The chart shows Hockey as 25% of the total. The total number of students is 200. To find the number of students who chose Hockey, calculate 25% of 200. Calculation: 0.25 * 200 = 50. Let's adjust the answers for this. A: 40, B: 25, C: 50, D: 70. Correct is C. Explanation: The pie chart indicates that 25% of students chose Hockey. To find the actual number, multiply the total number of students by the percentage: 200 students * 0.25 = 50 students.
Question 4: The table below shows the daily high temperatures for a city over five days. What was the average (mean) high temperature for this five-day period?
- 18°C
- 19°C (Correct answer)
- 20°C
- 21°C
Correct answer: 19°C
To find the average (mean) temperature, first, add all the daily high temperatures together: 18 + 22 + 20 + 15 + 20 = 95. Then, divide the sum by the number of days, which is 5. Calculation: 95 / 5 = 19. The average high temperature was 19°C.
Question 5: The double bar chart shows the quarterly sales for two products, Product A and Product B. In which quarter was the difference in sales between Product A and Product B the greatest?
- Quarter 2
- Quarter 4
- Quarter 1
- Quarter 3 (Correct answer)
Correct answer: Quarter 3
Calculate the sales difference for each quarter: Q1: 500 (A) - 400 (B) = 100. Q2: 600 (A) - 550 (B) = 50. Q3: 400 (A) - 700 (B) = 300. Q4: 800 (A) - 700 (B) = 100. The greatest difference is 300, which occurred in Quarter 3.
Question 6: The line graph below shows the number of visitors to a national park from 2018 to 2023. Which of the following statements best describes the overall trend in the number of visitors during this period?
- The number of visitors remained constant.
- The number of visitors showed a consistent decrease.
- The number of visitors generally increased. (Correct answer)
- The number of visitors fluctuated without any clear trend.
Correct answer: The number of visitors generally increased.
Observing the line graph from left (2018) to right (2023), the data points generally move upwards. Although there is a small dip between 2020 and 2021, the number of visitors in 2023 is significantly higher than in 2018, indicating an overall increasing trend.
