  1. In a pie chart, a sector represents 25% of the data. What is its central angle?

    Answer: 90°

    25% of 360° = 0.25 × 360 = 90°.

  2. What is the mode of this dataset: 3, 5, 5, 7, 8, 5, 9?

    Answer: 5

    The mode is the most frequently occurring value. 5 appears three times, more than any other.

  3. Two dice are rolled. What is the probability that the sum is 7?

    Answer: 1/6

    There are 6 combinations that sum to 7 out of 36 total outcomes: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1). So 6/36 = 1/6.

  4. A line graph shows temperatures of 60°F, 65°F, 70°F, and 68°F over four days. What is the average?

    Answer: 65.75°F

    Average = (60 + 65 + 70 + 68) / 4 = 263 / 4 = 65.75°F.

  5. If an event has a probability of 0.3, what is the probability it does NOT happen?

    Answer: 0.7

    The complement rule: P(not A) = 1 - P(A) = 1 - 0.3 = 0.7.

  6. A scatter plot shows a downward trend from left to right. This indicates:

    Answer: A negative correlation between the variables

    A downward trend means as one variable increases, the other decreases — a negative correlation.
