## Overview and objectives

In this course we'll go through the lifecycle of A/B testing and how to tackle experimentation questions in the interview. At the end we'll focus on some general statistical knowledge and questions that occur in data interviews.

## Audience

The audience for this course is anyone that wants a comprehensive understanding of A/B testing and statistics across multiple domains and case studies.

## Courses

Courses in this learning path are:

### Introduction to Statistics and A/B Testing

In this lesson, we're going to go over problems you might face in interviews focused on A/B testing and statistics.

### A/B Testing & Experiment Design

Let's start with a general framework for A/B testing. In practice, an A/B testing and experimentation all follow a step by step process of setting metrics and designing experiments.

### Confidence Intervals

Confidence intervals help us deal with this imprecision by giving us a way to talk about a range of values with some certainty where the true value of the statistic is contained in.

### A/B Testing Common Scenarios

The next couple of chapters will cover common scenarios and concepts involved in A/B testing. As A/B testing involves statistical concepts, there may be terms that you need refreshing on.

### Data Analytics Fundamentals: Causal Inference

In this course we’ll go over the core concepts of causality, significance, and analyzing data. This is meant as a quick refresher and a high level overview of causal inference basics to eventually apply them in data analytics problems.

2 of 9 Completed

### Generalized Linear Models and Regression

Regression models are used to predict the value of a dependent variable from one or more independent variables.
