Use Case: Diagnosing Root Causes Behind Declining NPS
Uncover what’s truly driving dissatisfaction — with statistical clarity.
.
The Challenge
Your NPS dropped — but from where? And why?
Dashboards show trends, but not truths. Without precision, improvement efforts miss the mark.
Our Analytical Approach
We apply structured statistical techniques to detect hidden patterns — and separate what feels important from what statistically is.
Here's how we do it:
-
Driver Regression Analysis:
Quantify which factors (e.g., onboarding clarity, support quality, usability) significantly influence NPS. -
Chi-Square Testing:
Assess whether differences in promoter/detractor distribution are statistically significant across experience variables. -
Correlation Heatmaps:
Visualize strength of relationships between experience scores and NPS. -
Text Mining + Sentiment Scoring:
Analyze open comments using NLP to discover negative sentiment drivers (e.g., “confusing setup,” “slow resolution”).
Statistical Insights Example
We ran a multivariate regression for a mid-sized B2B SaaS client with NPS data and experience metrics from 800 customers.
Key Results:

Onboarding and usability were statistically significant predictors of NPS.
Support mattered, but less so — suggesting prioritizing product fixes over support changes.
Drilldown Using Chi-Square
We compared Detractors vs. Promoters on onboarding experience:
-
72% of Detractors reported onboarding as unclear or somewhat clear
-
Only 19% of Promoters reported the same
Chi-Square p-value = 0.0002 → strong evidence that onboarding clarity affects promoter likelihood.
Actionable Takeaways
-
Prioritize onboarding redesign: customers unclear on setup were 3.6x more likely to become detractors.
-
Simplify UI elements where customers reported usability blockers.
-
Refine support process — but not before fixing foundational journey gaps.
