bar graph
A graph that uses the height or length of rectangles to compare data.
A bar graph is a type of chart or graph that represents data using rectangular bars of different heights or lengths. In a bar graph, the horizontal axis represents the categories being compared, while the vertical axis represents the values being measured. The bars can be either vertical or horizontal, depending on the orientation of the graph.
Bar graphs are often used to display categorical or discrete data, such as the number of students in each grade level, the distribution of a sample population by age or income, or the sales figures of different products during a specific time period. They can be used to compare the values of different categories or to track changes in values over time.
Bar graphs can be simple or complex depending on the type and amount of data being presented. The bars can be grouped by categories, stacked to show the total value, or clustered to show the comparison between different groups. The colors and patterns used in bar graphs can also be used to visually represent different categories or subcategories of data.
Overall, bar graphs are a useful tool for representing data in a clear and concise way, allowing viewers to quickly and easily understand relationships between different categories or values.
