A bar graph is the representation of numerical data by rectangles (or bars) of equal width and varying height. The gap between one bar and another should be uniform throughout. It can be either horizontal or vertical. The height or length of each bar relates directly to its value.
Bar graphs are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars are proportional to the measure of data. They are also known as bar charts. Bar graphs are one of the means of data handling in statistics.
Each bar represents a summary value for one discrete level, where longer bars indicate higher values. Types of summary values include counts, sums, means, and standard deviations. Bar charts are also known as bar graphs. Bar charts highlight differences between categories or other discrete data.
A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart. A bar graph shows comparisons among discrete categories.
A bar graph, also called a bar chart, represents data graphically in the form of bars. The height of the bars corresponds to the data they represent. Like all graphs, bar graphs are also presented on a coordinate plane having an x-axis and a y-axis.
A bar graph is a chart that compares different categories of data using rectangular bars that represent the value of the data.
Bar graph is a way of representing data using rectangular bars where the length of each bar is proportional to the value they represent. The horizontal axis in a bar graph represents the categories and the vertical bar represents the frequencies.
