Which plot visually represents the range measurements such as Median, Q1, Q3, Minimum, and Maximum?

• A. Histogram
• B. Box plot
• C. Scatter plot
• D. Bar chart

Answer: (B)

The box plot is specifically designed to visually represent the distribution of a dataset through summary statistics such as the median, first quartile (Q1), third quartile (Q3), minimum, and maximum values. This type of plot provides a clear and concise summary of the central tendency and variability of the data. In a box plot, the central box represents the interquartile range (IQR), which encompasses the middle 50% of the data between Q1 and Q3. The line within the box indicates the median, providing insight into the dataset's midpoint. Whiskers extending from the box show the range of the data, reaching to the minimum and maximum values, excluding any outliers, which may be plotted as individual points. Other plot types, while useful for various purposes, do not convey this summary information as effectively. For instance, a histogram displays the frequency distribution of numerical data but does not provide a direct visualization of the five-number summary. A scatter plot shows individual data points to visualize relationships between two variables, and a bar chart compares categorical data counts or values but lacks the summary statistics relevant to range measurements. Thus, the box plot stands out as the most appropriate choice for representing these specific range measurements.
