Using advanced statistics, this tool will confirm if the change is real:

• Excel based so it's easy to use.
• Uses two different statistical tests
  • Test 1: Margin of Error
  • Test 2: Chi-Squared Test on Net Promoter data

To use just enter the number of Promoters, Neutrals, Detractors in your survey.
