  1. A data set has values 4, 8, 8, 10, 20. What is the median?

    Answer: 8

    The median is the middle value of the ordered set, which is 8.

  2. Which measure of center is most affected by an extreme outlier?

    Answer: Mean

    The mean uses every value, so a single extreme outlier shifts it strongly.

  3. A bar graph shows sales of 30, 45, 25, and 50. What is the total?

    Answer: 150

    Adding 30 + 45 + 25 + 50 gives 150.

  4. What is the mode of the data set 2, 3, 3, 5, 7, 7, 7, 9?

    Answer: 7

    The value 7 appears most frequently (three times), so it is the mode.

  5. On a pie chart, a category occupies a 90° slice. What percent of the whole is it?

    Answer: 25%

    90° out of 360° equals one quarter, or 25%.

  6. The range of the set 12, 18, 7, 25, 10 is what?

    Answer: 18

    Range equals the maximum (25) minus the minimum (7), which is 18.

  7. A line graph rising steadily from left to right indicates what about the data?

    Answer: An increasing trend

    A line moving upward over time shows values that are increasing.
