# Descriptive Statistics for Data-driven Decision Making with Python

#### “Data is like garbage! You’d better know what you’re going to do with it before you collect it.” ~ Mark Twain

This is not a typical reference book for descriptive statistics. Instead, we take an in-depth look at what methods you would be foolish not to use in data science or machine learning. In this book, we dive into descriptive statistics with Python and an overview of what is crucial to know to obtain the most advantage of what we show you.

Descriptive statistics is essential for decision making based on data. Using descriptive statistics will give you a way to make straightforward decisions on your decision making without complex methodology. Descriptive statistics form the fundamental platform for every quantitative data analysis.

"Diving into Descriptive Statistics with Python" is a book by Pratik Shukla and Roberto Iriondo. Between us, we have worked together for the past year to create this material and prepare you for straightforward, data-driven decision making.

Please know that this is an experience-based, opinionated book. We only cover topics that will help you make the most out of using descriptive statistics for data-driven decision making.
