Question

Which type of chart is most suitable for statistical summary, including quartiles?

• A. Line Plot
• B. Box Plot
• C. Pie chart
• D. Scatter Plot

Hint:

Quartiles are drawn in a box plot (box and whisker).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
A statistical summary lists the minimum, first quartile (Q1), median, third quartile (Q3) and maximum of the data. We need to find the chart that shows all of these values together.

Step 2: Check option 1.
A line plot joins points to show how a value changes, usually over time. It does not show quartiles. So option 1 is wrong.

Step 3: Check option 2.
A box plot (box and whisker plot) draws a box from Q1 to Q3, a line at the median, and whiskers to the minimum and maximum. It shows the five-number summary and outliers. So option 2 is correct.

Step 4: Check option 3.
A pie chart shows each part as a share of the whole. It has no quartiles. So option 3 is wrong.

Step 5: Check option 4.
A scatter plot shows dots for pairs of values to show the relation between two variables. It does not show quartiles. So option 4 is wrong.

Step 6: Final Answer:
The chart that shows the statistical summary with quartiles is the box plot, which is option 2. \[ \boxed{2} \]
