Confidence-Adjusted Rankings: the Wilson Lower Bound for Positive Shares
This lesson is part of the course
In this lesson
You calculate the share of positive reviews per product, its Wilson lower bound – the share you can be fairly sure of – and rank the products by that bound, so a perfect 8 out of 8 no longer beats 801 out of 900.
