Statistics is a field of study that deals with the collection, analysis, and interpretation of data. It involves using mathematical techniques to summarize and describe data, as well as to draw conclusions and make predictions about a population based on a sample of data. The main goals of statistics are:
Why do we sample? Because checking every single person in a country (a census) is often impossible. Statistical methods teach us how to pick a representative group so our results remain accurate.
