Warn Deleted Reviews

Warn Rating Trend

  • 21%
  • Created over 215 days

We counted 6,941 reviews for this product over the span of 7,266 days, an average of 1.0 review per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 5 or fewer reviews on any given day.

However, we see the following 215 days exceeding this threshold:In total, we found that 1,476 reviews were created on just 215 days. This is an excessively high number of reviews submitted on these high volume days.

Warn Reviewer Participation

  • 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 2885 reviewers (or 42%) are within an overrepresented participation group. While this is more reviews from overrepresented participation groups than we'd expect to see, the discrepancy in ratings between reviewers in an overrepresented participation groups and all other reviewers isn’t significant enough to rule out the possibility of it being due to random chance.
