Study Notes
Statistics and Statistical Analysis
- Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of numerical or quantitative data.
- Statistical Analysis is the process of developing an understanding of what the data represents through the use of statistical methods.
Types of Statistical Analysis
- Descriptive Analysis: provides a summary of what the data represents, involving measures such as:
- Central Tendency
- Dispersion
- Skewness
- Inferential Analysis: involves making inferences, or generalizations, about data, involving measures such as:
