Now if you want to show SD or SEM, you may have spotted that the built-in standard deviation and standard error options above are not very good ways of going about it. Importantly, note that this standard error is based on the totals of the columns, NOT the original data, even if you have included that in the spreadsheet. This will give you the same value for each bar, the same value above and below the bar, and will be centered on the mean (average) of the sum of all the columns. This will give you different values for each bar, the same value above and below the bar, and will be centered on the top of the bar. This will give you the same value for each bar, the same value above and below the bar, and will be centered on the top of the bar. There are a few options for choosing the error amount of your error bars in PowerPoint: Enter a fixed value Finally, you can choose the error amount. You can also choose whether you want them capped or not. Working from the top down, you can first choose which direction the errors bars should go in. PowerPoint offers lots of options for customising the style of your error bars. Step 3: Edit your graph/chart’s error bars in PowerPoint Make sure the chart icon at the top of the pane is the one that is selected. When you click the button, choose More options and a formatting pane should open on the right-hand side of PowerPoint. Or you can use the button on the graph itself: You can add them in a couple of different ways. Step 2: Tell PowerPoint you want error bars on your chart or graphĮrror bars count as a chart element. It’s based on this data – and I’ve just plotted the average for each type of food. This is my chart – it’s a simple clustered column one with an entirely fictional dataset (that may perhaps show my own bias a teeny bit…).

If you’re not sure how to do this, then check out our free resource on creating graphs and charts (we also run a free masterclass on this, so check out the schedule to see when it is next on). I’m going to assume that you already know how to choose a chart or graph in PowerPoint and add your own data to it. In this article, I’ll show you how to add error bars in Excel and PowerPoint as the method is almost exactly the same in both programs. Statistics packages will do this for you, but what if you want to create the graph using good old Microsoft programs? Well, happily, it’s very easy to add error bars in PowerPoint – thanks to its leveraging of Excel functionality you can create good-looking charts that are accurate and useful. You do this by showing error bars on your graph, commonly standard deviation (SD), standard error of the mean (SEM), or confidence intervals (CI).
When you’re showing data on a graph or chart, particularly in a scientific context, it’s often important to show the variance of the data.
