I am trying to follow this answer: How can I calculate margin of error in a NPS (Net Promoter Score) result?
The data I have:
- 58 Promoters (48% of the total)
- 22 Neutrals (18% of the total)
- 41 Detractors (34% of the total)
- 14.05 NPS
The calculations from the answer in the question above become:
- NPS: 0.14
- Var(NPS): 0.80
- MoE/Standard error: 1.32
And the answer in the question suggest that I should be 95% confident that the survey result (sample NPS) is within 2.64% (MoE*2) of the population NPS (the surveys).
I am failing to see what this actually means though. Can anyone enlighten me of how to use the result, or what significance it has for drawing conclusions?
