Question 89 of 986
DA0-002 Visualization and Reporting Practice Question
Which TWO visualization types are suitable for showing the distribution of a single continuous variable?
⚠ Common exam trap
CompTIA often tests the distinction between visualization types by presenting a line chart as a distractor, tempting candidates to confuse trend visualization with distribution analysis, especially when the continuous variable is time-based.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Box plot
A box plot is correct because it graphically depicts the distribution of a single continuous variable through its five-number summary (minimum, first quartile, median, third quartile, maximum), clearly showing spread, central tendency, and outliers. A histogram is correct because it bins the continuous variable into intervals and displays the frequency of data points within each bin, providing a direct view of the underlying probability distribution.
