How To Add Error Bars In Excel- How to fix?

Anyone who frequently uses Excel will be familiar with the task of creating graphs and charts to display data. However, it’s not just placing the data on a graph that matters; often it’s about accurately representing the variability of that data. This is where error bars come into the picture. Error bars provide a visual representation of the variability of data and are essential to any scientist or statistician wanting to show the spread of data points. Now, the question arises – how to add error bars in Excel? This article intends to resolve your dilemma by providing a comprehensive and step-by-step guide to add error bars in Excel.

Understanding Excel Error Bars

Error bars in Excel indicate the degree of error or uncertainty in a measurement. They highlight the variability of the collected data and help users to get a better understanding of the difference between individual data points. Excel offers two types of error bars: Standard Error and Percentage.

Adding Error Bars to a Chart in Excel

Adding error bars in Excel may seem like a complex task, but with clear instructions and a little practice, you can easily add them to your charts. Here are the steps to follow:

  1. First, open your Excel workbook and select the chart where you want to add error bars.
  2. After selecting the chart, go to the ‘Chart Tools’ section and click on ‘Design’.
  3. In the ‘Chart Layouts’ group, find the ‘Add Chart Element’ option and click on it.
  4. Upon clicking ‘Add Chart Element,’ a drop-down menu will appear. From that menu, go to ‘Error Bars’ and select ‘More Error Bars Options…’.
  5. Now, you can choose between the different types of error bars: Standard Error, Percentage, or Custom options, depending on your specific needs.

Customising Error Bars in Excel

The functionality of Excel error bars doesn’t end at just representing the variability of data. They can be customized as well. Whether you want to change their color, style, or end style, Excel offers a wide range of customization options to make your error bars truly represent the data. To customise the error bars:

  1. Select your chart with the error bars.
  2. Go to the ‘Format’ menu under ‘Chart Tools.’
  3. In the drop-down menu, click on the ‘Shape Outline’ option to change the color of your error bars.
  4. Under the same ‘Shape Outline’ option, you can also change the weight (thickness) of your error bars.

Tips to keep in mind while using Excel Error Bars

While adding and customising error bars in Excel is not overly complicated, there are a few things users should bear in mind to make the most of this feature.

  • It’s paramount to remember that error bars are not a definitive measure of reliability or significance; nevertheless, they effectively give a sense of the data’s variability.
  • The type of error bars you should add to your chart largely depends on your data set – if your data points are spread out, percentage error bars might be a better choice, whereas standard error bars might prove more useful for closely-knit data.

Hope this guide on how to add error bars to Excel has eased your way to effectively incorporate this feature in your data representation tasks. Embrace the power of Excel and make the best of your data analysis journey.
