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.
