Course 2 5 hours

Descriptive Statistics

Learn how to describe data in terms of data types, measures of center, measures of spread, shape, and outliers. These essential skills in descriptive statistics provide the foundation for more advanced statistical techniques that are used for data science, data analysis, and machine learning.

Lesson 1

Introduction

In this lesson, we kick off the course with an introduction to data and descriptive statistics.

Lesson 2

Data Types

In this lesson, we establish key distinctions between different types of data, including quantitative, categorical, ordinal, nominal, continuous, and discrete data types.

Lesson 3

Measures of Center

In this lesson, we get into the calculations and use cases for three popular measures of center: mean, median, and mode.

Lesson 4

Notation

In this lesson, we demystify the mathematical notation used for random variables, observed values, and aggregations.

Lesson 5

Measures of Spread

In this lesson, we get into the calculations and use cases for several popular measures of spread, including five-number summaries, standard deviation, and variance.

Lesson 6

Shape and Outliers

In this lesson, we cover two additional forms of descriptive statistics for data distributions: shape and outliers.

Course 3 10 hours

Probability

This course is a comprehensive dive into the fundamental concepts and principles of probability. You’ll begin with basic probability theory, then progress to more complex topics such as binomial distributions, conditional probability, and Bayes’ Rule. These skills will enhance your ability to reason about uncertainty and make claims using data.

Lesson 1

Introduction

In this lesson, we start off with meeting the instructors and a high-level overview of probability.

Lesson 2

Probability Basics

In this lesson, you'll gain the basics of probability using coins and die.

Lesson 3

Binomial Distribution

In this lesson, you'll learn about one of the most popular distributions in probability - the Binomial Distribution.

Lesson 4

Conditional Probability

Not all events are independent. In this lesson, you'll learn the probability rules for dependent events.

Lesson 5

Bayes Rule

In this lesson, you'll learn one of the most popular rules in all of statistics - the Bayes Rule.

Course 4 15 hours

Experimentation

Experimentation is one of the most important topics in all of statistics because it tells us whether our conclusions are statistically significant. In this course, you will learn about the fundamental role statistics plays in experimentation as well as how to implement statistical concepts in Python.

Lesson 1

Introduction

In this lesson, we begin the course by meeting the instructors and giving a quick introduction to experimentation.

Lesson 2

Normal Distribution Theory

In this lesson, you'll learn the mathematics behind moving from a coin flip to a normal distribution.

Lesson 3

Sampling Distributions and the Central Limit Theorem

In this lesson, you'll learn all about the underpinning of confidence intervals and hypothesis testing - sampling distributions.

Lesson 4

Confidence Intervals

In this lesson, you'll learn how to use sampling distributions and bootstrapping to create a confidence interval for any parameter of interest.

Lesson 5

Hypothesis Testing

In this lesson, you'll learn the necessary skills to create and analyze the results of hypothesis testing.

Lesson 6

A/B Tests

In this lesson, you'll work through a case study of how A/B testing works in the context of website metrics for an online education company.
