Brand Repeats

142 of the 331 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.

Brand Loyalists

62 of the 331 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.

The Single-Day reviewers have rated this product an average of 9.7 while all other reviewers rated this product an average of 9.3. 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.

These reviewers have rated this product an average of 9.7 while the reviewers who have a more unique product review history rated this product an average of 9.3. 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.

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 -0.5 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.

Example critical reviews

0.1 average net helpfulness for positive reviews

-0.5 average net helpfulness for negative reviews

Deleted Reviews

Reviews have been deleted

We discovered a total of 9 deleted reviews for this product, with an average rating of 9.7. 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.

Word Count Comparison

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: 39.6% (Avg. rating: 9.5)

In total, we found that 131 reviews (or 40%) 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.

Created over 2 days

We counted 331 reviews for this product over the span of 3,195 days, an average of 0.1 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 2 or fewer reviews on any given day.

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

4 reviews on Aug 1, 2013 (Avg. rating: 9.0)
3 reviews on Jul 31, 2013 (Avg. rating: 9.3)

In total, we found that 7 reviews were created on just 2 days. This is within an acceptable range and it does not appear to be significantly affecting the overall rating for this product.
