How to Add Standard Deviation Error Bars in Excel

A graph’s error bar is a line drawn through a point that is parallel to any of the axis that depicts the degree of uncertainty or variance in the point’s corresponding coordinate. On the other hand, the standard deviation means the variation that occurs in the statistics. When the standard deviation is low, the data points lead to being extremely close to the mean, and when it is high, the data are dispersed over a wide range of values. You can show standard deviation error bars in the form of a chart in Excel. In this article, we are going to show the steps to generate the standard deviation error bars in Excel. So, let’s get started.
