What is statistics?

Statistics is the science of collecting, analyzing, interpreting, and presenting data.

What are the main types of statistics?

The two main types are descriptive statistics, which summarize data, and inferential statistics, which draw conclusions from samples.

Can beginners learn statistics online?

Yes. Beginner courses typically cover averages, variability, probability, distributions, and basic hypothesis testing.

What is the difference between probability and statistics?

Probability predicts possible outcomes, while statistics uses observed data to estimate patterns and make decisions.

What topics are covered in an applied statistics course?

Applied statistics often includes descriptive analysis, regression, hypothesis tests, ANOVA, sampling, and real-world data interpretation.

Why is statistics important for data science?

Statistics helps data scientists understand uncertainty, evaluate models, test assumptions, and make reliable conclusions from data.

What is Bayesian statistics?

Bayesian statistics updates the probability of a hypothesis as new evidence becomes available, using prior knowledge and observed data.
