What Is Statistics?
Statistics is the science of collecting, analyzing, interpreting, presenting, and organizing data. It helps us make informed decisions based on data rather than conjecture. In practical terms, statistics can involve anything from calculating averages to creating complex predictive models. The field is divided into descriptive statistics, which summarize data, and inferential statistics, which make predictions or inferences about a population based on a sample.
