Analysis Details
Fail Deleted Reviews
We discovered a total of 38 deleted Reviews for this product, with an average rating of 3.4. 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:
- 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.
- We have no information on reviews that were never published in the first place.
- 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.
Fail Suspicious Reviewers
One-Hit Wonders
8 of the 136 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 2.0 while the reviewers who have posted more than one review have rated this product an average of 3.5. 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.
Take-Back Reviewers
29 of the 136 reviewers have had at least one of their past reviews for another product deleted. The Take-Back Reviewers have rated this product an average of 3.9 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 3.3. 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.
