Fail Deleted Reviews

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 9, while the average ease score for reviewers in this category is 8.8. 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.

Fail 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 found that the negative reviews had an average net helpfulness score of -0.4 while the positive reviews had an average net helpfulness score of 0.2. Based on our statistical modeling, this discrepancy is significant enough to believe that the difference is not due to random chance, but possibly due to influence of unnatural voting patterns.
