  1. A spinner has 4 equal sections numbered 1–4. What is the probability of landing on an even number?

    Answer: 1/2

    Two of four outcomes (2 and 4) are even, so 2/4 = 1/2.

  2. The mean of a data set is greater than its median. The distribution is likely what?

    Answer: Skewed right

    When the mean exceeds the median, a long right tail pulls the mean up.

  3. A bar graph compares 4 cities' populations. Which feature lets you compare them quickly?

    Answer: Relative bar heights

    Comparing bar heights is the fastest way to read a bar graph.

  4. What is the mean of 14, 18, 22, and 26?

    Answer: 20

    The sum is 80, divided by 4 gives a mean of 20.

  5. In a data set, the first quartile (Q1) marks what?

    Answer: The 25th percentile

    Q1 is the value below which 25% of the data falls.

  6. A table shows 60 out of 240 customers chose option A. What percent is that?

    Answer: 25%

    60 divided by 240 equals 0.25, or 25%.

  7. Which of these is a measure of spread rather than center?

    Answer: Range

    Range measures how spread out the data is, not its center.
