Since the class intervals are usually a continuous range of values, unlike bar charts, the rectangular pars are not spaced (i.e.

The data should be grouped according to this interval, then a frequency of the data that fall into these groups will be taken. When constructing a histogram chart, the first thing to do after data collection is to determine the bins or class intervals.

The rectangular bars show the number of data points that fall into a specified class interval.Īlso known as a histogram chart, the class intervals (or bins) are not always of equal size across the horizontal axis. What is a Histogram Graph?Ī histogram graph is a graph that is used to visualize the frequency of discrete and continuous data using rectangular bars. Therefore, this article will cover details about what a histogram is and how we can create them digitally using Excel. This graph can be generated manually by drawing it with a straight ruler, or digitally using Excel.Ĭonstructing a histogram is quite easy when done digitally. Histograms provide a visual representation of quantitative data by using the height of neatly joined rectangular bars to indicate the frequency of points in a class interval. The case is quite different for histograms, which is mostly used to visualize large datasets of discrete and continuous data. One of the major setbacks of various data visualization methods is that they become increasingly difficult to read with larger datasets.
