  1. A data set contains the values: 4, 7, 7, 9, 13. What is the median?

    Answer: 7

    The median is the middle value when data is ordered; with 5 values, the 3rd value (7) is the median.

  2. What is the mean of the data set: 10, 20, 30, 40, 50?

    Answer: 30

    Mean = sum ÷ count = (10 + 20 + 30 + 40 + 50) ÷ 5 = 150 ÷ 5 = 30.

  3. A bar graph shows 40 students prefer math, 25 prefer science, and 35 prefer English. What percentage prefer science?

    Answer: 25%

    Total students = 40 + 25 + 35 = 100; 25 ÷ 100 = 25%.

  4. Which measure of central tendency is most affected by extreme outlier values?

    Answer: Mean

    The mean is calculated using all values, so a single extreme outlier can significantly raise or lower the average.

  5. A bag contains 5 red marbles and 3 blue marbles. What is the probability of randomly drawing a red marble?

    Answer: 5/8

    Probability = favorable outcomes ÷ total outcomes = 5 ÷ (5 + 3) = 5/8.

  6. What is the mode of the data set: 3, 7, 3, 9, 7, 3, 5?

    Answer: 3

    The mode is the value that appears most frequently; 3 appears three times, more than any other value.
