Data science is a key part of the world of STEM. You may have heard it described as the “sexiest job of the twenty-first century”. In this collection of tutorials, we’ll take a look at the field of data science, the key skills, and provide an introduction to using Python and R for data science.

Data Science: An Introduction

Preface

Data science is a key part of the world of STEM (science, technology, engineering, and mathematics). You may have heard it described as the “sexiest job of the twenty-first century”. There’s a soaring demand for data scientists, and the role involves a wide variety of skills. However, the day-to-day job of a data scientist—the impact of their work, and the most effective way to collaborate with them—can be a mystery within an organization.

Data Science for Everyone

There’s a joke going around in the Python community that says “Python is generally the second-best language for everything you can imagine!”

Python for Data Science: an Introduction to Pandas

With increased computing power comes increased access to large amounts of freely accessible data. People are tracking their lives with productivity, calorie, fitness and sleep trackers. Governments are publishing survey data left and right, and companies conduct audience testing that needs analyzing. There’s a lot of data out there even now, ready to be grabbed and looked at.

Introduction to R and RStudio

With the craze for "big" data , analytics tools have gained popularity. One of these tools is the programming language R . In this guide, I’ll show how to extract data from text files, CSV files, and databases. Then I’ll show how to send that data to a web server.

How to Import Data and Export Results in R

Once you’ve gathered the data for your project, what are the next steps? How can you sanitize your data before you perform further analysis on it? With any new data set, the first operation to perform is exploratory data analysis (EDA). The EDA process involves summarizing the main characteristics of the data.
