Here is a short tutorial on how to create a column chart with standard deviation bars in Ms Excel 2011 for Mac. It used for presenting the mean and overall distribution of several grouped data.

Error bars are a useful and flexible tool that help add detail to an Excel chart. A typical use for error bars is to show variability in the measures which are plotted in the chart. There are other ways to use error bars to embellish Excel charts, as listed at the end of this article. This article was written based on the error bar system in Excel 97 through 2003. If you are using Excel 2007, you will have noticed a lot of differences from earlier versions, particularly in charting. Error bars have been changed substantially, to the extent that Excel 2007 users have had a lot of problems finding and applying error bars. I have written a new article about. Adding Error Bars Error bars are easy to add to a chart series. Double click on the series, or select the series and press CTRL+1, to open the Format Series dialog. Most chart types allow Y error bars, and XY Scatter types allow X error bars as well. The Error Bar dialogs, shown below, are not at all complicated. These dialogs allow you to display no error bars, positive error bars, negative error bars, and error bars in both directions. There are several ways to enter values: fixed values, a percentage of the point's value, a number of standard deviations, the standard error of the plotted points, and custom values. As a means of explaining these options, each will be shown using the following simple data set, which results in a basic series of points. You should make up your own data set to practice making error bars. C D E F 2 X Y Xerr Yerr 3 1.6 1.97 0.897 0.897 4 2.51 3.1 0.732 0.732 5 3.55 2.79 0.633 0.633 6 3.83 3.96 0.6 0.6 7 5.47 4.4 0.633 0.633 8 5.77 5.72 0.732 0.732 9 6.89 7.2 0.897 0.897 10 7.76 7.65 1.128 1.128 11 8.78 8.34 1.425 1.425 This is a simple XY Scatter chart of the sample data set, without error bars. This shows our sample chart with positive and negative X and Y error bars, with a fixed value of 0.75. This shows our chart with positive and negative X and Y error bars, using a percentage of 12%. As the data values increase from the bottom left to the top right, the length of the error bars, 12% of the value, also increases. Here is our chart with error bars of one standard deviation. This chart differs from the rest, because the error bars do not start at the data points and move away from them. Ye meri zindagi tu mere sath he mp3 song. For each data point, the X error bars are centered on the average of the X values, and they extend left and right by one standard deviation of X (5.13 ± 2.43, or 2.70 to 7.56); likewise the Y error bars are centered on the average of the Y values (5.01), and extend up and down by one standard deviation of Y (5.01 ± 2.31, or 2.71 to 7.32). For clarity, the chart is redrawn with only the Y error bars. This chart shows the standard error of the plotted points as the error bar value for each point. Excel doesn't document how this is calculated, but you can consult a statistics text. Custom Error Bar Values If you have a more complicated set of values for your error bars, you enter them using the Custom (+) and Custom (-) boxes.
