Analysis Details


Fail Reviewer Participation

  • 42%
  • 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 31 reviewers (or 42%) are within an overrepresented participation group. These reviews have rated this product an average of 2.2, while all other reviews have rated this product an average of 3.8. 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.

  • Created over 1 day

We counted 73 reviews for this product over the span of 768 days, an average of 0.1 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 2 or fewer reviews on any given day.
