Fail Suspicious Reviewers

One-Hit Wonders


131 of the 1,246 reviewers have only reviewed this product. While this is more One-Hit Wonders than we'd expect to see, it does not appear to have a significant impact on the overall rating.

Fail Reviewer Ease
The ease score is the average rating for all reviews that a given reviewer submits. The average ease score for reviewers of this product is 4.5, while the average ease score for reviewers in this category is 4.4. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.

Pass Skewed Helpfulness
We examined the average net helpfulness score of negative reviews against the average net helpfulness score of positive reviews. The net helpfulness score is the number of times a review has been marked as helpful minus the number of times a review has been marked as unhelpful. We could not find any statistically significant difference in average net helpfulness score between the negative reviews and positive reviews.

Pass Incentivized Reviews
On Oct 3, 2016, Amazon prohibited incentivized reviews, however we still test for them since there are still millions in our dataset.

We didn't detect any reviews that used language indicating they were incentivized.
