- Data visualization: histograms, bar charts, scatter plots, boxplots.
Probability Concepts
Probability forms the basis for making inferences from data. Key topics include:
- Basic probability rules.
- Conditional probability and independence.
- Bayes’ theorem.
- Discrete probability distributions, especially the binomial distribution.
- Continuous distributions, with an emphasis on the normal distribution.
Sampling Distributions and the Central Limit Theorem
Understanding the behavior of sample statistics is crucial for inference:
- Concept of sampling distributions.
- The Central Limit Theorem and its significance.
- Standard error and its calculation.
- Applications in real-world scenarios.
Estimation and Hypothesis Testing
These are the core techniques for drawing conclusions from data:
- Point estimates and confidence intervals.
- Hypothesis testing procedures.
- Types of errors: Type I and Type II.

- P-values and significance levels.
Regression Analysis and Correlation
Analyzing relationships between variables helps in prediction and understanding:
- Scatter plots and correlation coefficients.
- Simple linear regression modeling.
- Interpreting regression output.
- Residual analysis and assumptions.
Analysis of Variance (ANOVA) and Nonparametric Tests
When comparing multiple groups or data that do not meet parametric assumptions:
- One-way ANOVA.
