  1. A survey asked 200 students their favorite sport. 80 chose soccer. What is the relative frequency for soccer?

    Answer: 0.40

    80 ÷ 200 = 0.40, so the relative frequency for soccer is 0.40 (or 40%).

  2. A histogram has bars of heights 3, 7, 12, 8, and 5 for intervals 0–10, 10–20, 20–30, 30–40, and 40–50. In which interval do most data values fall?

    Answer: 20–30

    The tallest bar (height 12) corresponds to the 20–30 interval, meaning the most data values fall there.

  3. Which statement about a data set with a symmetric, bell-shaped distribution is true?

    Answer: The mean, median, and mode are approximately equal

    In a perfectly symmetric bell-shaped (normal) distribution, the mean, median, and mode are all equal.

  4. A two-way table shows data for 100 students by grade (7th/8th) and whether they own a pet (yes/no). If 40 are 7th graders and 25 of them own a pet, what fraction of 7th graders own a pet?

    Answer: 5/8

    25 out of 40 seventh graders own a pet: 25/40 = 5/8.

  5. Which graph type is best suited for showing how a quantity changes over time?

    Answer: Line graph

    Line graphs are specifically designed to display changes in a quantity over continuous time intervals.

  6. A data set is: 2, 5, 6, 6, 8, 9, 100. Which measure of center best represents the typical value?

    Answer: Median

    The outlier 100 greatly inflates the mean, so the median (6) better represents the typical value.

  7. On a dot plot, each dot represents one data value. If a category has 6 dots and the total is 24, what percentage of the data does that category represent?

    Answer: 25%

    6 ÷ 24 = 0.25, which equals 25%.
