If you’re looking for variability, standardization and sampling distributions chapter notes, then you’re definitely in the right place. These notes are not only for my fellow Bertelsmann Udacity Data Science Scholarship students that maybe are just beginning or simply they want to go through the material once more but for any of you that expressed an interested in this subject. Variability Variability measures how much your scores differ from each other. In other words refers to how spread out a group of data is. Measures of Variability: Range Range is the simplest measure of variability. You take the smallest number and subtract…

Bertelsmann Udacity Data Science Scholarship Summarily   What is Data Science? Data Science is an interdisciplinary field that brings together tools, processes, and systems to extract insights from data. It involves concepts from a variety of fields, ranging from mathematics/statistics to computer science and programming to machine learning, through to visualization and presentation. At its core, Data Science involves using automated methods to analyze massive amounts of data and to extract knowledge from them. Who needs Data Science capabilities? Data is everywhere. The amount of data we create is going to increase exponentially in the years ahead. The ability to…
