Analysis Details

Fail Deleted Reviews

  • 11
  • Reviews have been deleted

We discovered a total of 11 deleted Reviews for this product, with an average rating of 4.6 . 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.

17

of the

reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.

Warn Rating Trend

  • 7%
  • Created over 2 days

We counted

55 reviews

for this product over the span of

3,697 days

, an average of 0.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 1 or fewer reviews on any given day.

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

  • 2 Reviews on Mar 29, 2017 (Avg. rating: 5.0 )
  • 2 Reviews on Jul 31, 2017 (Avg. rating: 5.0 )

In total, we found that

4 reviews

were created on just

2 days

. 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.



Warn Suspicious Reviewers

Take-Back Reviewers

  • 35%
  • have previously deleted reviews

19

of the

55

reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, the discrepancy in ratings between the Take-Back Reviewers and reviewers who don't have any deleted reviews in their history isn't significant enough to rule out the possibility of it being due to random chance.



Warn Word Count Comparison

  • 44%
  • Have an overrepresented word count

In the graph above, we can see the distribution of review word counts for this product and the expected distribution for this category. We see the following 1 group with a statistically significant greater concentration than what we'd expect to see:

  • 0-5 words : 43.6% (Avg. rating: 4.7 )

In total, we found that 24 reviews (or 44%) are within an overrepresented word count group. While this is more reviews from overrepresented word count groups than we'd expect to see, the discrepancy in ratings between reviews with overrepresented word groups and all other reviews isn't significant enough to rule out the possibility of it being due to random chance.
