A histogram is useful in displaying a large amount of data in a more comprehensible way, which is easy to visualize. read more, the end-use of a histogram is very different from that of a bar chart. To create a bar chart, we need at least two independent and dependent variables. Although a histogram looks quite similar to a bar chart Bar Chart Bar charts in excel are helpful in the representation of the single data on the horizontal bar, with categories displayed on the Y-axis and values on the X-axis. The concept of a histogram equation is very useful as it is used to portray a set of data. Let’s see some simple to advanced examples to understand the calculation of the histogram equation better. Finally, the area for the histogram equation is calculated by adding the product of all the frequency density and their corresponding class width.Įxamples of Histogram Formula (with Excel Template).Then, derive the frequency density for each interval by dividing the frequency by the corresponding class width. Next, develop a table or spreadsheet with frequencies for each interval.Now, determine the width of the interval class by dividing the range of the data sample by the number of intervals.Ĭlass width = Range / Number of intervals.
As a thumb rule, use 10 as the number of intervals or -The number of intervals can be calculated by the square root of the number of data points, which is then rounded off to the nearest whole number.
Once decided, the data is gathered and presented in a tabular form, such as a spreadsheet. Firstly, it is to be decided on how the process should be measured and what data should be collected.
