Question

which visualization tool is best for understanding the distribution of a single variable? a. line graph b. histogram c. scatter plot d. box plot

Explanation:

• A line graph is used to show trends over time.
• A scatter plot is used to show the relationship between two variables.
• A box plot shows the distribution of data based on quartiles but does not show the full distribution as comprehensively as a histogram for a single variable.
• A histogram divides the range of a single variable into intervals (bins) and shows the frequency of data points in each bin, making it ideal for understanding the distribution of a single variable.

Answer:

b. Histogram
