  1. A bar graph shows monthly rainfall totals: Jan=2in, Feb=3in, Mar=5in, Apr=4in. Which month had the highest rainfall?

    Answer: March

    March had 5 inches of rainfall, which is greater than January (2), February (3), and April (4).

  2. A pie chart shows how a student spends 24 hours: Sleep 33%, School 25%, Homework 17%, Free Time 25%. How many hours does the student spend on homework?

    Answer: 4.08 hours

    17% of 24 hours = 0.17 × 24 = 4.08 hours.

  3. A line graph shows a city's population growing from 10,000 in 2000 to 15,000 in 2010. What was the percent increase?

    Answer: 50%

    Percent increase = (15,000 − 10,000) / 10,000 × 100 = 50%.

  4. A table shows test scores for 5 students: 72, 85, 90, 68, 95. What is the median score?

    Answer: 85

    Arranged in order: 68, 72, 85, 90, 95 — the middle (third) value is 85.

  5. A double bar graph compares boys' and girls' favorite sports. If 40 boys and 25 girls chose soccer, how many total students chose soccer?

    Answer: 65

    Total students = 40 boys + 25 girls = 65 students.

  6. A frequency table shows the number of books read per month: 0 books=5 students, 1 book=8 students, 2 books=4 students, 3 books=3 students. How many students were surveyed in total?

    Answer: 20

    Total = 5 + 8 + 4 + 3 = 20 students.

  7. A scatter plot shows a positive correlation between hours studied and test grades. What does a positive correlation indicate?

    Answer: As hours studied increase, grades also increase

    A positive correlation means both variables move in the same direction — more study hours are associated with higher grades.
