## Course

Deepen your analytical skills with this beginner-friendly course in real-world statistics. This course will teach you the statistical concepts & techniques you need to conduct rigorous inferential analyses and draw accurate conclusions from data sets.

## What You Will Learn

1. ### Statistics for Data Science

1 month to complete

A solid foundation in statistics is essential to making sense of data in any field, but most courses focus on theory, rather than modern use cases. This course is designed to cut through the noise and teach you the concepts and techniques you need to know to tackle common real-world challenges, such as analyzing AB tests and building regression models.

#### Prerequisite knowledge

Python & SQL.

• ##### Binomial Distribution

Learn about binomial distribution where each observation represents one of two outcomes and derive the probability of a binomial distribution.

• ##### Bayes Rule

Build on conditional probability principles to understand the Bayes rule and derive the Bayes theorem.

• ##### Sampling Distributions and Central Limit Theorem

Use normal distributions to compute probabilities and the Z-table to look up the proportions of observations above, below or in between values.

• ##### Hypothesis Testing

Use critical values to make decisions on whether or not a treatment has changed the value of a population parameter.

• ##### T-Tests and A/B Tests

Test the effect of a treatment or compare the difference in means for two groups when we have small sample sizes.

• ##### Logistic Regression

Use logistic regression results to make a prediction about the relationship between categorical dependent variables and predictors.

• ##### Course Project: Analyze A/B Test Results

In this project, you will be provided a dataset reflecting data collected from an experiment. You’ll use statistical techniques to answer questions about the data and report your conclusions and recommendations in a report.
