Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I thoroughly enjoyed this book. I found a lot to agree with. It did give me a new look at country living. I have always preferred the city since coming to Australia as an English migrant in the late 60s. Thank you I will look at the country I visit with new eyes.
