Elaboration:

Number of positive features : This value equals to the sum of all the green marked features for an item. For every product, there are some positive(marked green) and negative(marked red) features. We summed up all the green marked features to calculate this value. Rating frequencYes : This value indicates how frequently a product is receiving every 10 ratings on Amazon.com. This gives an idea of how frequently a product is getting sold on Amazon. Usually one of every 10 persons that purchases a product rates it. A lower value here means the product is getting sold at a faster rate. All these data were collected on 24 th December, 2018. Blank/white Boxes : The boxes that are white indicate that we didn't find mention of those features anywhere on the internet for those products when we conducted our research. We couldn't come to a conclusion about those features when we personally tested them as well. So we left them blank/white. Price : Price on Amazon.com on 24th December, 2018. Average Rating : The average rating it has out of 5 on Amazon.com till 24 th December, 2018. Total reviews : The total number of ratings/reviews it received on Amazon.com till 24 th December, 2018. P.S. For some points where positive or negative cant be determined easily (for example rating frequency, price etc.), we took an average value and made everything that is equal or above that value green and anything lower than that red.
