A bar graph that shows the upper and lower limits in a data set is called a:

• A. Line chart
• B. Bar graph
• C. Scatter plot
• D. Histogram

Answer: (D)

A histogram is a type of bar graph used to display the distribution of a continuous variable by grouping data into intervals. The height of each bar shows how many observations fall into that interval, which helps you see the overall spread from the smallest to the largest value in the data set. This makes the range—the upper and lower limits—visible at a glance, along with how the data are concentrated within that range. Line charts emphasize trends over time, scatter plots show relationships between two variables, and bar graphs compare categories rather than a distribution of a continuous variable, so they don’t convey the data’s spread in the same way.
