Analysis Details


Fail Suspicious Reviewers

One-Hit Wonders


60 of the 242 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 4.3 while the reviewers who have posted more than one review have rated this product an average of 3.4. 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.

Take-Back Reviewers


13 of the 242 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, it does not appear to have a significant impact on the overall rating.

Fail Reviewer Participation

  • 48%
  • From reviewers with an overrepresented participation

We see the following 1 participation group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 115 reviewers (or 48%) are within an overrepresented participation group. These reviews have rated this product an average of 3.9, while all other reviews have rated this product an average of 3.4. 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.

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 -5.8 while the positive reviews had an average net helpfulness score of 6.9. 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.

-5.8 average net helpfulness for negative reviews
