Analysis Details

Fail

• 3
• Reviews have been deleted

We discovered a total of 3 deleted Reviews for this product, with an average rating of 3.3. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.

There are a few limitations to keep in mind regarding the Deleted Reviews test:

1. We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
2. We have no information on reviews that were never published in the first place.
3. We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.

• 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 12 reviewers (or 33%) are within an overrepresented participation group. These reviews have rated this product an average of

. 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.

However, we see the following 2 days exceeding this threshold:

• 2 Reviews on May 5, 2018 (Avg. rating: 5.0)
• 2 Reviews on Jul 6, 2019 (Avg. rating: 5.0)

In total, we found that

. Although any days with a larger number of reviews than expected is suspicious, the discrepancy in ratings from reviews created on these high volume days and reviews created on other days isn't significant enough to rule out the possibility of it being due to random chance.
