What Is Statistics?
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, and presentation of masses of numerical data. It provides methodologies to gather data, summarize it, and make sense of it in a way that can be communicated clearly to inform decisions. Whether through descriptive techniques like averages and percentages or inferential methods like hypothesis testing, statistics helps transform data into actionable insights.
