Statistical Inference: How to Draw Conclusions from Data

Can you trust your data? This **Johns Hopkins course** teaches the core principles of statistical inference: probability, variability, confidence intervals, hypothesis testing, and resampling methods—so you can distinguish real signals from noise.

Key Concepts

  • Probability—conditional probability, Bayes’ rule
  • Expectation & variance—the language of uncertainty
  • Confidence intervals—quantify estimation uncertainty
  • Hypothesis testing—p-values, type I/II errors, power
  • Resampling—bootstrapping and permutation tests

Why This Matters

Without inference, data science is just pattern-spotting. This course gives you the **rigor to make credible claims**.

Who Is This For?

  • Researchers designing experiments
  • Analysts evaluating A/B tests
  • Data scientists needing to validate model performance
  • Students in the JHU Data Science Specialization

Think Like a Statistician

You’ll learn to ask: “Could this have happened by chance?”—and answer it confidently.
