In scatter plots and bubble charts, both vertical and horizontal error bars can be displayed. In Microsoft Excel, error bars can be inserted in 2-D bar, column, line and area graph, XY (scatter) plot, and bubble chart. In other words, error bars can show you how far from the reported values the actual values might be. For this, they calculate confidence intervals, or margins of error, and display them by using what is known as error bars. And because scientists love quantifying things, they found a way to quantify uncertainty.
In science, uncertainty is the beginning of an investigation. In medicine, it generates innovations and leads to technological breakthroughs.
In business, it prepares your company for the future. In truth, uncertainty is not a bad thing. Many of us are uncomfortable with uncertainty because it is often associated with lack of data, ineffective methods or wrong research approach. You will learn how to quickly insert standard error bars, create your own ones, and even make error bars of different size that show your own calculated standard deviation for each individual data point. The tutorial shows how to make and use error bars in Excel.
