Study Notes
Statistics Overview
- Statistics involves the collection, organization, analysis, interpretation, and presentation of data.
- Populations can consist of diverse groups such as all individuals in a nation or every atom in a material.
- Representative sampling ensures valid inferences can be made about the population from the sample.
Statistical Methods
- Two primary statistical methods are:
- Descriptive statistics: Summarizes sample data using indices like mean or standard deviation.
- Inferential statistics: Draws conclusions from data with inherent random variation.
Data Collection
- When census data is unattainable, statisticians design specific experiments and surveys to gather necessary information.
