What type of graph is used to show the frequency distribution of data grouped into ranges?

• A. Histogram
• B. Line Chart
• C. Box Plot
• D. Bar Graph

Answer: (A)

A histogram is the correct choice for displaying the frequency distribution of data grouped into ranges, known as bins. This type of graph visually represents how often each range of values occurs within a dataset. Each bar in a histogram corresponds to a bin, and the height of the bar indicates the frequency or count of data points that fall within that range. The design of a histogram emphasizes the distribution of numerical data, which makes it particularly useful for understanding the shape of the data's distribution, identifying patterns such as skewness or modality, and recognizing any potential outliers. By grouping data into ranges, a histogram allows for a clearer visualization of how values are distributed, making it easier to interpret large sets of quantitative data. Other types of graphs serve different purposes: a line chart is typically used for showing trends over time, a box plot displays the five-number summary of data (minimum, first quartile, median, third quartile, and maximum), and a bar graph often represents categorical data rather than numerical data grouped into ranges. Each of these alternatives has its specific use cases but does not represent frequency distributions in the same way that a histogram does.
