Fail Suspicious Reviewers

One-Hit Wonders


Approximately 45% of reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 5.0 while the reviewers who have posted more than one review have rated this product an average of 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.
