Which plot shows each individual score as a dot and helps assess distribution shape?

• A. Density plot
• B. Histogram
• C. Scatter plot
• D. Box plot

Answer: (A)

Assessing the shape of a distribution is best done with a plot that shows how scores are spread across the range. A density plot does this by plotting the estimated density of scores along the horizontal axis, producing a smooth curve. You can quickly see if the distribution is symmetric or skewed and whether there are one or more peaks, which tells you about unimodality or multimodality. Because it smooths over bin choices, it often gives a clearer picture of the overall shape than a histogram. If you needed to display every individual score as a dot, a dot plot would be the direct choice, but that option isn’t listed here; among the given plots, the density plot best communicates the distribution’s shape.
