Every time you go to an online shopping site like Amazon, you
see the ratings of the products, the reviews of the customers etc.
All this data that you see is nothing but statistics.
Whenever you are planning a trip or a journey, you take in
account the weather conditions of the place. Since future telling
machines haven’t been invented till now, all the data you see is
due to the goodwill of statistics
Do you watch the weather forecast sometime during the day? How
do you use that information? Have you ever heard the forecaster
talk about weather models? These computer models are built using
statistics that compare prior weather conditions with current
weather to predict future weather.
Stock analysts also use statistical computer models
to forecast what is happening in the economy.
