Statistics Explained: Types, Uses and Importance

Statistics is a branch of mathematics that involves collecting, organising, analysing and interpreting data. It helps turn raw figures into useful information for better decision-making. Descriptive statistics summarises data from a specific group using averages, tables, charts and graphs. Inferential statistics uses data from a smaller sample to make estimates or predictions about a larger population. Statistics helps people identify patterns, measure risk and make informed choices. It is widely used in healthcare, business, government, education and scientific research.
