For the same matrix sizes (5-10), simpler average consistency indexes for each incomplete step [7] would require more information (108 different values).Arachnophobics, worry not — SPDRs aren’t at all what they sound like, and they’re certainly not as scary. If you’re in the process of learning more about investing, you might have come across something called SPDR index funds.It asks people how likely they are to recommend your company to someone they know. In an NPS survey, the customer chooses a score between 0 and 10. Detractors are people who select 0-6. Promoters choose 9-10. You can calculate the NPS by subtracting the percentage of detractors from the percentage of promoters.
