Designing an MS Excel spreadsheet for research data

The recommended layout for experimental data in an MS Excel spreadsheet has 3 components: experiment details, design factors and measurement variables. There is also a row where we will put short but relevantly named column titles. This will make it easier for future exp ort to a statistical software.

The recommended layout for survey data in an MS Excel spreadsheet is very similar to the one shown above. The 3 components are: survey details, survey descriptors and measurement variables. Again we include a row with short column titles.

  • Possible to add detailed documentation

  • Possible to use the full power of MS Excel:

    • error checking

    • copying formulas

    • summarising data (fast and easy Pivot Table)

    • visual exploration (very powerful Pivot Chart)

  • Easy to import when using statistical software
