  1. A scatter plot shows a cluster of points in the upper-right quadrant and another cluster in the lower-left quadrant. What does this pattern most likely indicate?

    Answer: A positive correlation between the two variables

    Points clustering in upper-right and lower-left quadrants indicate that as one variable increases, the other also tends to increase — a positive correlation.

  2. A pie chart shows four slices labeled A (45°), B (90°), C (135°), and D (90°). What percentage of the total does slice C represent?

    Answer: 37.5%

    A full circle is 360°, so slice C at 135° represents 135/360 = 37.5% of the total.

  3. On a double bar chart comparing male and female test scores across four grade levels, you notice the female bars are consistently taller. What conclusion is best supported?

    Answer: Females score higher on average across all grades

    If female bars are consistently taller across all four grade levels, the data supports that females score higher on average.

  4. A line graph shows sales rising steeply from January to March, then leveling off through June, then declining through December. Which term best describes the January–March segment?

    Answer: Upward trend

    A steep rise in data values over a period of time is called an upward trend.

  5. A histogram has bars of heights 5, 12, 20, 15, and 8 for five consecutive intervals. Which interval contains the mode class?

    Answer: Third interval

    The mode class in a histogram is the interval with the tallest bar, which is the third interval with a height of 20.

  6. A table shows five cities' populations and park areas. City X has 500,000 people and 250 acres of parks. What is its park-to-population ratio in acres per 1,000 residents?

    Answer: 0.5 acres per 1,000

    250 acres ÷ 500 (thousands of residents) = 0.5 acres per 1,000 residents.

  7. A box plot shows a median line very close to the top of the box (near the third quartile). What does this suggest about the data distribution?

    Answer: The data is negatively (left) skewed

    When the median is close to the upper quartile (Q3), most data is concentrated at the higher end, indicating left (negative) skew with a long tail toward lower values.
