What are two examples of data displays mentioned for describing data?

• A. Box plots and histograms.
• B. Line graphs and bar charts.
• C. Pie charts and scatter plots.
• D. Histograms and bar charts.

Answer: (A)

When describing data, we look for displays that show how the numbers are spread out and where the middle value lies. A histogram groups data into ranges and counts how many data points fall into each range, giving a quick view of the overall shape of the data—whether it’s concentrated in the middle, spread out, or skewed to one side. A box plot summarizes the spread with the minimum, first quartile, median, third quartile, and maximum, so you can see the center and how far the data reach, plus whether there are outliers. Together, these two displays provide a clear description of the data’s distribution. Other options focus on different ideas, like changes over time, comparisons across categories, parts of a whole, or relationships between two variables. They’re useful, but they don’t describe the distribution of a single data set as directly as histograms and box plots do. So the two examples most helpful for describing data are histograms and box plots.
