Analysis Details


Fail Rating Trend

  • 29%
  • Created over 15 days

We counted 658 reviews for this product over the span of 212 days, an average of 3.1 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 10 or fewer reviews on any given day.

However, we see the following 15 days exceeding this threshold:In total, we found that 192 reviews were created on just 15 days. The reviews on these high volume days have rated this product an average of 4.6 while reviews from other days have rated this product an average of 4.2. 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.
