Excel Histogram Charts and FREQUENCY Function July 20, 2011 by Mynda Treacy 22 Comments A Histogram, also known as a frequency distribution, is a chart that illustrates the distribution of values that fall into groups.
The tutorial shows 3 different techniques to plot a histogram in Excel - using the special Histogram tool of Analysis ToolPak, FREQUENCY or COUNTIFS function, and PivotChart. While everyone knows how easy it is to, making a histogram usually raises a bunch of questions. In fact, in the recent versions of Excel 2016, Excel 2013, and Excel 2010, creating a histogram is a matter of minutes and can be done in a variety of ways - by using the special Histogram tool of the Analysis ToolPak, formulas or the old good PivotTable. Further on in this tutorial, you will find the detailed explanation of each method. • • • • • • • What is a histogram in Excel? Defines a histogram in the following way: ' Histogram is a graphical representation of the distribution of numerical data.'
Absolutely true, and totally unclear:) Well, let's think about histograms in another way. Have you ever made a bar or column chart to represent some numerical data? I bet everyone has. A histogram is a specific use of a column chart where each column represents the frequency of elements in a certain range. In other words, a histogram graphically displays the number of elements within the consecutive non-overlapping intervals, or bins. For example, you can make a histogram to display the number of days with a temperature between 61-65, 66-70, 71-75, etc.
Degrees, the number of sales with amounts between $100-$199, $200-$299, $300-$399, the number of students with test scores between 41-60, 61-80, 81-100, and so on. The following screenshot gives an idea of how an Excel histogram can look like: How to create a histogram in Excel using Analysis ToolPak The Analysis ToolPak is a Microsoft Excel data analysis add-in, available in all modern versions of Excel beginning with Excel 2007. However, this add-in is not loaded automatically on Excel start, so you would need to load it first. Load the Analysis ToolPak add-in To add the Data Analysis add-in to your Excel, perform the following steps: • In Excel 2010, Excel 2013, and Excel 2016, click File > Options. In Excel 2007, click the Microsoft Office button, and then click Excel Options. • In the Excel Options dialog, click Add-Ins on the left sidebar, select Excel Add-ins in the Manage box, and click the Go button. • In the Add-Ins dialog box, check the Analysis ToolPak box, and click OK to close the dialog.

One-Way ANOVA Step-by-Step Example Imagine you manufacture paper bags and you want to improve the tensile strength of the bag. • Interprets the Results: QI Macros performs the calculations AND tells you: • If you can Reject or Not Reject the Null Hypothesis • Means are the Same or Different • Draws Chart to Visualize the Results: QI Macros draws a box plot of your data to help you visualize and understand the results of your One Way ANOVA test.
If Excel shows a message that the Analysis ToolPak is not currently installed on your computer, click Yes to install it. Now, the Analysis ToolPak is loaded in your Excel, and its command is available in the Analysis group on the Data tab.
Specify the Excel histogram bin range Before creating a histogram chart, there is one more preparation to make - add the bins in a separate column. Bins are numbers that represent the intervals into which you want to group the source data (input data). The intervals must be consecutive, non-overlapping and usually equal size.
Excel's Histogram tool includes the input data values in bins based on the following logic: • A value is included in a certain bin if it is greater than the lowest bound and equal to or less than the greatest bound for that bin. • If your input data contain any values greater than the highest bin, all such numbers will be included in the More category. • If you do not specify the bin range, Excel will create a set of evenly distributed bins between the minimum and maximum values of your input data range. Considering the above, type the bin numbers that you want to use in a separate column. The bins must be entered in ascending order, and your Excel histogram bin range should be limited to the input data range. In this example, we have order numbers in column A and estimated delivery in column B. In our Excel histogram, we want to display the number of items delivered in 1-5 days, 6-10 days, 11-15 days, 16-20 days and over 20 days.
