1 XL1F: Create Histogram using HISTOGRAM in Excel 2013 V0G 1 Create Histogram using HISTOGRAM in Excel 2013 Milo Schield Member: International Statistical Institute US Rep: International Statistical Literacy Project Director, W. M. Keck Statistical Literacy Project Demo and slides at: Excel2013-Create-Histogram-Using-HISTOGRAM-demo.pdf Excel2013-Create-Histogram-Using-HISTOGRAM-slides.pdf 2 The Goal and Approach Goal: Use Excel Toolpak HISTOGRAM command to summarize data and generate Excel histogram graph. Modify histogram to eliminate spaces between bars. Excel 2013 has two ways to summarize continuous data: 1. Using functions: COUNTIF or FREQUENCY 2. Using a command: Histogram in Data Analysis Compared to functions, the Toolpak command has One advantage: Easier/faster to create. Three disadvantages: Needs a manual update. Doesn t give ranges. Doesn t eliminate spaces between bars. 3 Use Excel Toolpak command: Create Histogram of Weight 4 Steps to Create a Histogram using HISTOGRAM command A. Determine the number of bins and the bin width B. Set bin maximums Data at: Histogram-Using-HISTOGRAM-Data.xlsx 1. Use Data Analysis Toolpak. Select HISTOGRAM 2. Enter data into HISTOGRAM command to: generate bin counts generate an Excel Histogram 3. Eliminate gaps between bars in Excel Histogram Modify caption on the horizontal axis. 5 A: Determine bin # & width: Enter formulas as shown. 6 B: Enter 1 st Bin Maximum; Generate Bin Maximums. 1
2 XL1F: Create Histogram using HISTOGRAM in Excel 2013 V0G 7 1: Data tab: Select Analysis Select Histogram 8 2a: Enter Data, Bin Maximums Output Range & Chart Output. 9 2b: Generate table and chart. Move chart on top of table 10 3a: Right-Mouse a column bar; Select Format Data Series 11 3b: Change Gap Width to zero. Result is a Histogram. 12 Conclusion Histograms display continuous data properly!. 2
3 XL1F: Create Histogram using HISTOGRAM in Excel 2013 V0G 13 Histogram versus Bar/Column Chart A bar or column chart involves bars that are separated because the data is categorical (e.g., male/female) or discrete numeric (e.g., # of kids in family). A histogram involves bars (horizontal or vertical) that can touch because the data is continuous numeric (e.g., heights or weights). Ordinal data (e.g., small, medium, large) can be displayed either way: with separated or touching bars. 3
