What is statistics?

Statistics is a branch of mathematics that involves collecting, analyzing, interpreting, and presenting data. It is used to make informed decisions, draw conclusions, and make predictions based on data. Statistics can be applied to a wide range of fields, including business, economics, social sciences, and natural sciences.

Statistics is the science of collecting, organising, analysing, interpreting, and presenting data. It involves the development of techniques to:

- Collect Data: Design surveys, experiments, and other methods to gather relevant data from populations or samples.

- Organise Data: Structure and present data in a meaningful way, such as tables, graphs, and charts, to make it easier to understand.

- Analyse Data: Use mathematical and statistical methods to examine the patterns, trends, and relationships within data. This involves techniques such as hypothesis testing, regression analysis, and statistical modelling.

- Interpret Data: Draw conclusions and make inferences based on the analysis results and consider the context and limitations of the data.

- Present Data: Communicate the findings and insights derived from data analysis effectively to various audiences, using presentations, reports, and visualisations.

The goal of statistics is to provide a systematic and objective understanding of data to inform decision-making, solve problems, and advance knowledge in various fields such as science, business, medicine, and social sciences.
