Why I created the Excel data analysis tool

During my day to day job I sometimes need to perform testing on a sample, analyse the data and summarise the results. Most of the times this is done to verify the accuracy of a filling equipment. After performing a series of doses (normally between 100 and 1000) I have to analyse some basic statistical data like average, standard deviation, relative standard deviation, etc. This allows to summarise the findings before presenting them to my colleagues.

The procedure to analyse the data in Excel is not particularly difficult, but needs some time to setup the spreadsheet, gather the data, write the formulas, create the charts and format the whole page to make it nice to present.

Excel data analysis spreadsheet and add-in were created to simplify this procedure. After activating the interface, the user selects the data and the place where to position the results. After inputting the data unit of measure, the results are ready to be printed.

The spreadsheet can automatically calculate:

  • Maximum value
  • Minimum value
  • Average
  • Variance
  • Standard deviation
  • Relative standard deviation (RSD and 3RSD)
  • Distribution

The spreadsheet can also automatically print charts:

  • Data plot
  • Frequency distribution histogram

All these values are calculated using Excel built-in functions. Thanks to that, the spreadsheet is interactive and automatically updates the results if the data is modified. Using an options menu the user can define which data to print. The settings are stored for next use.

Excel data analysis is available as a ready-to-use spreadsheet and as an add-in. This allows to perform the data analysis on every spreadsheet by just clicking on a button.
