Analysis Details


Fail Rating Trend

  • 39%
  • Created over 20 days

We counted 324 reviews for this product over the span of 1,110 days, an average of 0.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.

However, we see the following 20 days exceeding this threshold:In total, we found that 125 reviews were created on just 20 days. The reviews on these high volume days have rated this product an average of 4.3 while reviews from other days have rated this product an average of 4.0. 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.
