Note that you must right-click the histogram graph precisely on part of the graph in order for this command to be available: if you right-click a blank area of the histogram, the Export to Excel command appears instead, which you use to copy information from all of the graphs in the histogram to Excel. Right-click the histogram graph you want to export and select Export to Excel.As you can observe, the length of each column corresponds to the frequency of that particular bin. Step 4 − Click SERIES OPTIONS and change the Gap Width to 0 under SERIES OPTIONS. Step 3 − Right click on the Columns and select Format Data Series from the dropdown list. Step 2 − Insert a Clustered Column chart. Step 1 − Select the data in the Frequency table. Creating a Histogramįollowing are the steps to create a Histogram. This table is called a Frequency table and we will use it to create the Histogram. The number of values in a bin is referred to as the frequency of that bin. For example, Histogram can be used in statistical analysis in the following scenarios −Ī census of a country to obtain the people of various age groups.Ī survey focused on the demography of a country to obtain the literacy levels.Ī study on the effect of tropical diseases during a season across different regions in a state.Ĭreate bins and calculate the number of values in each bin from the above data as shown below − Histogram is used to inspect the data for its underlying distribution, outliers, skewness, etc. The rectangles are colored or shaded.Ī Histogram will be as shown below. Thus, the horizontal axis represents the bins whereas the vertical axis represents the frequency. A rectangle over a bin with height proportional to the frequency of the bin depicts the number of cases in that bin. The bins must be adjacent and are of equal size. The bins are usually specified as consecutive, non-overlapping intervals of the variable. The numerical intervals are called bins and the number of occurrences is called frequency. What is a Histogram?Ī Histogram is represented by rectangles with lengths corresponding to the number of occurrences of a variable in successive numerical intervals. In this case, when the source data is updated the chart also gets refreshed. In this chapter, you will learn how to create a Histogram from a Column chart. However, in such a case, when the data is updated, Histogram will not reflect the changed data unless it is modified through Analysis ToolPak again.
In Excel, you can create a Histogram from the Analysis ToolPak that comes as an add-in with Excel. It is widely used in Statistical Analysis.
A Histogram is a graphical representation of the distribution of numerical data.
