Tuning into signals from the tablet’s market noise

For a long time I was interested in correlation between numbers of products (units) sold and numbers of customer reviews for the product posted online and here I attempt to connect those dots.

Our aggregation algorithms found 1,299 customer reviews for Apple iPad and 294 customer reviews for Samsung Galaxy Tab. By applying 13% correction to the number of customer reviews found, and dividing the result by a number of iPads sold we can estimate that Apple had to sell just over 10,000 units to generate just 1 customer review (10,151).
