Verified step by step guidance1
Understand that the problem asks for the most common graph type used to display quantitative data grouped into ranges or intervals.
Recall that quantitative data refers to numerical data that can be measured and ordered, such as heights, weights, or test scores.
Recognize that when quantitative data is grouped into intervals (also called bins or classes), the goal is to show the frequency or count of data points within each interval.
Know that a histogram is specifically designed to display the distribution of quantitative data by grouping data into intervals and showing the frequency of data points in each interval with adjacent bars.
Compare other options: bar charts typically display categorical data, dot plots show individual data points, and pie charts represent parts of a whole, so they are less suitable for grouped quantitative data.
