Practice question · Select all that apply
Select every statement that is TRUE about data visualization.
Hints
- Two options are misconceptions - one swaps the histogram's job onto a bar chart, one praises a truncated axis.
- Distribution shape is the histogram's role, and a zero-based axis is what keeps a bar chart honest.
Show the answer
- A. A scatterplot is the natural chart for two continuous variables.
- C. A histogram's touching bars signal a continuous variable.
- E. A truncated y-axis can exaggerate a genuinely small difference.
Why
Touching bars, truncated-axis distortion, and scatterplots for two continuous variables are all true. A histogram (not a bar chart) shows one variable's distribution, and starting the axis above zero makes a bar chart LESS honest.
