Which two types of graphs are best used to visualize how data is distributed?

• A. $\text{Histogram and boxplot}$
• B. $\text{Scatterplot and line graph}$
• C. $\text{Stem-and-leaf plot and dot plot}$
• D. $\text{Pie chart and bar chart}$

Answer: (A)

Verified step by step guidance

1. Understand that visualizing data distribution means showing how data values are spread or arranged across different ranges or categories.
2. Recall that a histogram is a type of graph that groups data into bins or intervals and shows the frequency of data points in each bin, making it excellent for visualizing the shape of the data distribution.
3. Recognize that a boxplot (or box-and-whisker plot) summarizes data distribution by displaying the median, quartiles, and potential outliers, providing a clear picture of the data's spread and symmetry.
4. Note that other options like scatterplots and line graphs are better suited for showing relationships between variables or trends over time, rather than distribution.
5. Conclude that the best types of graphs for visualizing data distribution are the histogram and the boxplot.
