Study Notes
Inferential Statistics
- Uses sample data to draw inferences about a population
- Involves two key components: Parameter Estimates and Hypothesis Testing
Parameter Estimates
- Uses sample data to provide an estimate about a specific feature of a population
- Example: Estimating the effect of a new drug on relapse delay
- Types:
- Point Estimate: Provides a single value representing the best guess for the population parameter
- Interval Estimate: Provides a range of values that is likely to contain the population parameter
Hypothesis Testing
- Uses sample data to validate a hypothesis based on limited evidence
- Example: Testing whether a new drug delays relapse
- Types:
- Null Hypothesis: States that there is no relationship between variables
- Research or Alternative Hypothesis: States that there is a relationship between variables
