- Basic probability rules: Addition and multiplication rules
- Conditional probability: Events dependent on each other
- Discrete probability distributions: Binomial distribution
- Expected value and variance of distributions
3. Inferential Statistics
Inferential statistics allow students to make predictions or generalizations from sample data to a larger population:
- Sampling methods: Random, stratified, systematic, and cluster sampling
- Sampling distributions: Understanding how sample statistics behave
- Hypothesis testing: Null hypothesis, alternative hypothesis, significance levels, and p-values
- Confidence intervals: Estimating population parameters
4. Data Collection and Presentation
Accurate data collection and presentation are vital skills:
- Designing surveys and experiments
- Recognizing bias and errors
- Properly summarizing and presenting data for clarity and accuracy
