Hypothesis testing
Decisions can be made using gut feeling (instinct, guess, idea) or data driven, a simple example could be rolling 2 dice’s (cube) and predicting a single number (sum of the individual dice number), based on your gut feeling you might come with a single number but based on data driven decision you might choose 7 which has the highest probability. There could be many instances where decisions based on gut feeling would have given 100% success, but going with data driven decisions you can reduce the chances of failure. And the core of data driven decision making is Hypothesis testing.
What is Hypothesis testing?
“A statistical hypothesis test is a method of statistical inference used to decide whether the data at hand sufficiently support a particular hypothesis. Hypothesis testing allows us to make probabilistic statements about population parameters.” -Wikipedia
So basically, Hypothesis testing is like proving the gut feeling wrong based on the data which we collect :).
