Objectives to cover:
Introduction: Probability theory forms the mathematical foundation for modeling uncertainty in data science.
Random Variables and Their Types: Random variables represent outcomes and are classified as discrete or continuous based on their value sets.
Probability Mass Functions vs. Probability Density Functions: PMFs describe probabilities for discrete variables, while PDFs are used for continuous variables.
Expectation, Variance, and Standard Deviation: These metrics summarize the central tendency and spread of probability distributions.
The Law of Large Numbers and Central Limit Theorem: These theorems explain the behavior of sample averages and enable inference from data.
Hypothesis Testing and Confidence Intervals: Statistical tests and intervals support decision-making under uncertainty using sample data.
Correlation, Regression, and Their Probability Foundations: Relationships between variables are quantified using probability-based models.
Bayesian Inference in Data Science: Bayesian methods update probabilities with new evidence to support dynamic decision-making.
Conclusion: A solid grasp of probability enhances the effectiveness of data-driven insights and predictive modeling in data science.
