Let's consider the below example, which shows a chemistry lab trial test shown as follows.

Now calculate the Average and standard deviation to apply for the error bar by following the below steps.

• Create two new columns as Average and Standard Deviation
• Insert Average formula =AVERAGE(B2:F2) by selecting B2: F2.

• We will get the average output as follows.

• We will get the standard deviation as follows.

• Now select the Sucrose Concentration Column and AVG column by holding the CTRL-key.

• Go to the Insert menu. Select the Scatter Chart that needs to be displayed. Click on the scatter chart.

• We will get the result as follows.

• Close the dialogue box so that the above Error bar with percentage will be get increased by 15 percentage.
• In the below screenshot, Error Bar with Percentage shows 15 percentage Error Bar measurement of 1.0, 1.0, 0.0, -1.3 and at last with value -1.4 in blue color dots as shown in the below screenshot.

Example #3

In this example, we are going to see how to add an Error Bar with Standard Deviation in Excel.

Consider the same example where we have already calculated Standard deviation as shown in the below screenshot where it shows chemistry labs test trails with average and standard deviation.

We can apply an Error Bar with a Standard Deviation by following the below steps.

• First, select the Sucrose Concentration column and Standard deviation Column.
• Go to the Insert menu to choose the chart type and select the Column chart as shown below.

• We will get the below chart as follows.

• Now click on the Blue Colour bar so that we will get the dotted lines as shown below.

• Once we click on the selected dots, we will get the chart layout with the Error Bar option. Choose the fourth option, "Error Bars with Standard Deviation".

• So that we will get the below standard deviation measurement chart as shown in the below screenshot.

• To show the Error bar in Red Bar, follow the same process as illustrated above.

As we can notice that error bars showing a standard deviation of 0.5, 0.1, 0.2, 0.4 and 1.0

Things to Remember

• Error Bars in Excel can be applied only for chart formats.
• In Microsoft excel, error bars are mostly used in chemistry labs and biology, which are used to describe the data set.
