I'm trying to run some variance/standard error calcs for NPS (net promoter score) which is calculated as (# of promoters - # of detractors)/total surveys
How can I calculate margin of error in a NPS (Net Promoter Score) result?
I've calculated my standard deviation and variance using the page above, but I'm a bit confused one what it means.
So for example, let's say my NPS score is .331 or 33.1%.
I did my variance calculation using 0.331 as my NPS score, and it outputted a variance of:
variance = 0.842 standard deviation = 0.918
What do these numbers mean? And more specifically, if my input NPS is "0.331" does my standard deviation of 0.918 mean that my NPS score (33.1%) standard deviation 91.8%?
Sorry if the question is really beginner level, but trying to wrap my head around this.
Thank you
