Sample item

Which graph best displays the distribution of continuous blood-pressure values?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Histogram

A histogram groups continuous measurements into intervals, showing distribution shape, spread, skewness, and possible multiple peaks.

Option by option

  • A. Scatterplot of one variable only

    Scatterplots need two quantitative variables.

  • B. Pie chart

    Pie charts display categorical proportions.

  • C. Flow diagram

    Flow diagrams display processes rather than data distributions.

  • D. Histogram (correct)

    Correct: histograms display distributions of continuous values.
