Are there Free Excel Alternatives to Minitab for my Lean Six Sigma Green / Black Belt Project?

We get asked this question a lot. Many companies or individuals do not want to incur the expense for Minitab or other costly statistical analysis tools. Another reason this question is often asked is because most people are more comfortable with Microsoft Excel.

The answer to their question is YES … there is are free Microsoft Excel alternatives to Minitab for statistical analysis. Excel has an add-on called the Data Analysis Toolpack. Plus there are many templates that have been developed and are available on the web.

This is a reference to Microsoft Excel alternative tools and templates to Minitab statistical analysis that are taught in our Lean Six Sigma Green Belt and Black Belt course. You will find YouTube videos and websites explaining the different tools.

These statistical analyses are created in MS Excel using tools other than the Data Analysis Tool (i.e., using MS Excel’s different default graphing functions)

• Pareto Chart – https://www.youtube.com/watch?v=SDzBkjo8Qeo
• 2^nd Level Pareto Chart (Excel can’t perform this analysis)
• Box and Whiskers Plot – https://www.youtube.com/watch?v=EiS-q6euyf8.
• Time Series Plot – https://www.youtube.com/watch?v=gl28MOUyYu0
• Scatter Plot – https://www.youtube.com/watch?v=OVA2M7EIx80

These statistical analyses use the MS Excel Data Analysis Tool. We have also included an article explaining the different data analysis tool’s and how to load the MS Excel add-in.
