Excel It would be nice if all data was perfect, absolute and complete. But when it isn't, Excel gives us some useful tools to convey margins of error and standard deviations. If you work in a field that needs http://www.pryor.com/blog/add-error-bars-and-standard-deviations-to-excel-graphs/ to reflect an accurate range of data error, then follow the steps below to add Error Bars to your charts and graphs: Begin by creating your spreadsheet and generating the chart or graph you will be working http://www.ats.ucla.edu/stat/stata/faq/barcap.htm with. To follow using our example below, download Standard Deviation Excel Graphs Template1 and use Sheet 1. These steps will apply to Excel 2013. Images were taken using Excel 2013 on the Windows 7 OS. Click on the error bars chart, then click the Chart Elements Button to open the fly-out list of checkboxes. Put a check in the Error Bars checkbox. Click the arrow beside the Error Bars checkbox to choose from common error types: Standard Error – Displays standard error amount for all values. Percentage – Specify a percentage error range and Excel will calculate the error amount for each value. Default percentage is 5%. Standard Deviation – Displays standard deviation error amount error bars in for all values. Resulting X &Y error bars will be the same size and won't vary with each value. You can also turn on Error bars from the Add Chart Element dropdown button on the Design tab under the Chart Tools contextual tab. Blast from the Past: Error Bars function similarly in Excel 2007-2010, but their location in the user interface changed in 2013. To find and turn on Error Bars in Excel 2007-2010, select the chart, then click the Error Bars dropdown menu in the Layout tab under the Chart Tools contextual tab. Customize Error Bar Settings To customize your Error Bar settings, click More Options to open the Format Error Bars Task Pane. To follow using our example, download the Standard Deviation Excel Graphs Template1 and use Sheet 2. From here you can choose to: Set your error bar to appear above the data point, below it, or both. Choose the style of the error bar. Choose and customize the type and amount of the error range. Select the type of error calculation you want, then enter your custom value for that type.

bars? Say that you were looking at writing scores broken down by race and ses. You might want to graph the mean and confidence interval for each group using a bar chart with error bars as illustrated below. This FAQ shows how you can make a graph like this, building it up step by step. First, lets get the data file we will be using. use http://www.ats.ucla.edu/stat/stata/notes/hsb2, clear Now, let's use the collapse command to make the mean and standard deviation by race and ses. collapse (mean) meanwrite= write (sd) sdwrite=write (count) n=write, by(race ses) Now, let's make the upper and lower values of the confidence interval. generate hiwrite = meanwrite + invttail(n-1,0.025)*(sdwrite / sqrt(n)) generate lowrite = meanwrite - invttail(n-1,0.025)*(sdwrite / sqrt(n)) Now we are ready to make a bar graph of the data The graph bar command makes a pretty good bar graph. graph bar meanwrite, over(race) over(ses) We can make the graph look a bit prettier by adding the asyvars option as shown below. graph bar meanwrite, over(race) over(ses) asyvars But, this graph does not have the error bars in it. Unfortunately, as nice as the graph bar command is, it does not permit error bars. However, we can make a twoway graph that has error bars as shown below. Unfortunately, this graph is not as attractive as the graph from graph bar. graph twoway (bar meanwrite race) (rcap hiwrite lowrite race), by(ses) So, we have a conundrum. The graph bar command will make a lovely bar graph, but will not support error bars. The twoway bar command makes lovely error bars, but it does not resemble the nice graph that we liked from the graph bar command. However, we can finesse the twoway bar command to make a graph that resembles the graph bar command and then combine that with error bars. Here is a step by step process.First, we will make a variable sesrace that will be a single variable that contains the ses and race information. Note how sesrace has a gap between the levels of ses (at 5 and 10). generate sesrace = race if ses == 1 replace sesrace = race+5 if ses == 2 replace sesrace = race+10 if ses == 3 sort sesrace list sesrace ses race, sepby(ses) +---------------------------------+ | sesrace ses race | |---------------------------------| 1. | 1 low hispanic | 2. | 2 low asian | 3. | 3 low african-amer | 4. | 4 low white | |---------------------------------| 5. | 6 middle hispanic | 6. | 7 middle asian | 7. | 8 middle african-amer | 8. | 9 middle white | |---------------------------------| 9. | 11 high hispanic | 10. | 12 high asian |
