Most chart types allow Y error bars, and XY Scatter types allow X error bars as well. To add error bars to a selected data point or data series, click the data point or data series that you want, or do the following to select it from a By dividing the standard deviation by the square root of N, the standard error grows smaller as the number of measurements (N) grows larger. Error bars have been changed substantially, to the extent that Excel 2007 users have had a lot of problems finding and applying error bars.
