PowerPoint also allows error bars to be shown on all data points or data markers equally a standard error amount, a per centum, or a standard deviation. Displaying variances in information is useful equally y'all can encounter mutual standard deviations, standard error of the mean, or confidence intervals. Remember, error bars are regarded by PowerPoint equally chart elements, so you tin can add them in a variety of means. The two easiest are through the top ribbon or by the button on the graph. Let's await at both.
