💡 Key Takeaways
- Interpret and apply advanced statistical models (e.g., regression, ANOVA, Bayesian methods) to real data.
- Assess hypothesis tests using power, effect size, confidence intervals, and p-values.
- Diagnose and validate models through residual analysis, assumption checks, and goodness-of-fit metrics.
- Utilize resampling and robust techniques such as bootstrapping and cross-validation.
❓ Frequently Asked Questions
What is the difference between descriptive and inferential statistics?
Descriptive statistics summarize the data you have (e.g., mean, median, spread, charts). Inferential statistics use sample data to draw conclusions about a population, quantifying uncertainty with tools like confidence intervals and p-values.
What is a p-value and how should I interpret it?
The p-value is the probability, under the null hypothesis, of obtaining data as extreme or more extreme than observed. A small p-value suggests the result is unlikely under the null, but it does not prove causation or measure effect size.
What is a confidence interval and how should I read it?
A confidence interval is a range that, in repeated sampling, would contain the true parameter a specified percentage of the time (e.g., 95%). It indicates precision and uncertainty for the current study.
How do correlation and causation differ?
Correlation measures an association between two variables. Causation means one variable directly affects another. Correlation does not imply causation due to possible confounding, bias, or reverse causation.
