This weekend, I did some research on customer ratings on 3 popular ecommerce websites of India: Flipkart, Amazon and Snapdeal. I wanted to record the ratings and see if I can deduce any interesting patterns. Before starting this research, I did not really have an objective. I was not sure if I would get anything interesting out of this or not. It was more of an experiment than anything else.
Firstly, I could see that electronics and books had the most number of ratings. So, most of my recordings were focussed on these two segments so that I have enough data to validate.
One strikingly interesting thing I observed: For any good electronic product with decent no. of ratings, the shape of the ratings almost always is like this:
Peculiar shape emerged for customer ratings of electronic products from Flipkart, Amazon and Snapdeal.
For almost every product, no. of 5 star ratings were more than 4 star, followed by 3 and 2 but there is an increase in 1 star ratings.
