Analysis Details

Note: While Amazon claims 79,070 reviews, we counted 59,318 available on their site.

Fail Rating Trend

  • 61%
  • Created over 199 days

We counted 59,318 reviews for this product over the span of 1,521 days, an average of 39.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 61 or fewer reviews on any given day.

However, we see the following 199 days exceeding this threshold:In total, we found that 36,435 reviews were created on just 199 days. The reviews on these high volume days have rated this product an average of 4.2 while reviews from other days have rated this product an average of 3.2. 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.

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 -0.1. 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.
