# Statistical Essentials of Data Science¶

If we use a transportation metaphor we might say that statistics and machine learning are the vehicles that take us to both new and familiar places. We could also think of programming and software engineering as the roads and infrastructure necessary to make travel even possible. Linear algebra and basic statistics on the other hand aligns well with the motors and engines that propel our vehicles.

## Statistics¶

The materials we cover dig into the basics, introducing the areas of probability and statistics that are common to many data science learning paths. In addition to the content here, we provide a listing of resources for further study that review and reinforce these topics. Mastery of all this material is crucial for forming a strong foundation for statistics, machine learning, data science, or any other analytical and data-oriented discipline.

We’ll will be taking a tour of the fundamental concepts in probability
and *counting*, followed by core statistical concepts. We will gain
some familiarity with statistical distributions and how they are used.
Finally we will conclude the with an introduction to hypothesis
testing and linear models.
