Why Add Standard Deviation Bars in Excel?

Standard deviation bars are essential in data visualization as they provide a quantitative measure of the uncertainty or variability in your data. By adding these bars to your charts, you can:

  • Show the range of values within which most data points fall
  • Highlight the reliability of your data
  • Compare the variability of different data sets
  • Identify outliers and anomalies

Method 1: Using the Built-in Error Bar Feature

Excel provides a built-in feature to add error bars to your charts. This method is straightforward and easy to use.

Adding Error Bars using the Built-in Feature

To add error bars using the built-in feature:

  1. Select your data range and go to the "Insert" tab.
  2. Click on the "Chart" button and select the chart type you want to use.
  3. Click on the chart to select it, and then click on the "Chart Elements" button.
  4. Check the box next to "Error Bars" to add error bars to your chart.
  5. Right-click on the error bars and select "Format Error Bars."
  6. In the "Format Error Bars" pane, select the type of error bar you want to use (e.g., standard deviation, percentage, etc.).
  7. Choose the number of standard deviations you want to display (e.g., 1, 2, or 3).

Method 2: Using a Formula to Calculate Standard Deviation

If you want more control over the calculation of standard deviation, you can use a formula to calculate it.

Calculating Standard Deviation using a Formula

To calculate standard deviation using a formula:

  1. Select the cell where you want to calculate the standard deviation.
  2. Type the formula =STDEV.S(range) where range is the range of cells you want to calculate the standard deviation for.
  3. Press Enter to calculate the standard deviation.
  4. Select the cell with the standard deviation value and go to the "Home" tab.
  5. Click on the "Number" group and select "Number" to format the cell as a number.

Method 3: Using a Macro to Add Standard Deviation Bars

If you want to automate the process of adding standard deviation bars, you can use a macro.

Adding Standard Deviation Bars using a Macro

To add standard deviation bars using a macro:

  1. Open the Visual Basic Editor by pressing "Alt + F11" or by navigating to "Developer" > "Visual Basic."
  2. In the Visual Basic Editor, click on "Insert" > "Module" to insert a new module.
  3. Paste the following code into the module:
Sub AddStandardDeviationBars()
    Dim chart As Chart
    Dim series As Series
    Dim errorBars As ErrorBars
    
    Set chart = ActiveChart
    Set series = chart.SeriesCollection(1)
    Set errorBars = series.ErrorBars
    
    errorBars.Clear
    errorBars.Add xlStdDev
End Sub
  1. Click on "Run" > "Run Sub/UserForm" to run the macro.
  2. Select the chart you want to add standard deviation bars to.
