It highlights the relationship between data groups and statistical values.A bar chart represents data categories using vertical or rectangular bars that are proportional to numerical values.Typically, one axis of the graph details specific data categories while the other axis highlights the measured value for comparison.

In some instances, the bar chart can be plotted in clusters to show more than one measured group of data. This means that the length or height of each bar is proportionally equivalent to the data that it represents. Typically, the data in a bar graph is represented using vertical or horizontal bars that are plotted in accordance with the statistical value of each data category. It is a common statistical tool used for data categorization and it often highlights the differences in the numerical values of specific groups of data.

What is a Bar Chart or Graph?Ī bar chart or bar graph is a diagrammatic representation of data in quantities. It is important for researchers to know how to plot a bar graph as well as the different types of bar graphs that are available. Specifically, it breaks categorical data sets into groups based on numerical differences, and it is made up of response and predictor variables. This tool helps researchers to effectively manage large sets of data by categorizing them based on their numerical values.

A bar graph is the most common method of statistical representation and it is used to create visual presentations of quantifiable data variables.
