What is Statistical Enquiry?
A statistical enquiry is a systematic process where data is gathered, analyzed, and interpreted to answer a research question or understand a specific phenomenon. It is essential in economics and business for making data-backed decisions and understanding trends.

- Planning: Design the enquiry process (method, sources, tools to use).
- Data Collection: Gather relevant data from primary or secondary sources.
- Data Analysis: Organize and analyze the collected data using suitable statistical techniques.
- Interpretation and Reporting: Draw conclusions, present the results, and suggest actions.
