Get ready to master classic interview concepts ranging from conditional probabilities to A/B testing to the bias-variance tradeoff, and much more! You’ll work with a diverse collection of datasets including web-based experiment results and Australian weather data. Following the course, you’ll be able to confidently walk into your next interview and tackle any statistics questions with the help of Python!

Prerequisites

Hypothesis Testing in PythonSupervised Learning with scikit-learn
1

Probability and Sampling Distributions

This chapter kicks the course off by reviewing conditional probabilities, Bayes' theorem, and central limit theorem. Along the way, you will learn how to handle questions that work with commonly referenced probability distributions.
Start Chapter
2

Exploratory Data Analysis

In this chapter, you will prepare for statistical concepts related to exploratory data analysis. The topics include descriptive statistics, dealing with categorical variables, and relationships between variables. The exercises will prepare you for an analytical assessment or stats-based coding question.
Start Chapter
3

Statistical Experiments and Significance Testing

Prepare to dive deeper into crucial concepts regarding experiments and testing by reviewing confidence intervals, hypothesis testing, multiple tests, and the role that power and sample size play. We'll also discuss types of errors, and what they mean in practice.
Start Chapter
4

Regression and Classification

Wrapping up, we'll address concepts related closely to regression and classification models. The chapter begins by reviewing fundamental machine learning algorithms and quickly ramps up to model evaluation, dealing with special cases, and the bias-variance tradeoff.

FAQs

What types of statistics interview questions does this course cover?

The course covers conditional probabilities, Bayes theorem, central limit theorem, A/B testing, confidence intervals, hypothesis testing, the bias-variance tradeoff, and regression and classification concepts.

Is this course designed for people actively preparing for job interviews?

Yes. The exercises simulate analytical assessments and stats-based coding questions you would encounter in data science interviews, using Python for all solutions.

What datasets are used in the practice exercises?

You will work with web-based experiment results and Australian weather data among other datasets to practice answering interview-style statistics questions.

Does the course go beyond probability into machine learning topics?

Yes. The final chapter covers regression and classification models, model evaluation techniques, handling special cases, and the bias-variance tradeoff.

What prerequisites should I complete before this advanced course?

You need pandas, hypothesis testing, sampling, basic statistics, and supervised learning with scikit-learn. Strong foundations in these areas are essential for the interview-level exercises.
