Course Description
Knowing how data can impact the future is important. Making informed decisions can turn failing businesses around or make fledgling businesses thrive. Recognizing which data is vital to collect and organizing that data into relevant information can enable you to not only analyze your current situation but also make realistic forecasts for the future. Understanding this is key to making the best possible decisions and to knowing how to acquire the necessary data consistently.
In this course on Variables, you will gain awareness of the connection between variables and decision-making. You’ll learn the different kinds of variables, the information they can convey, and how to make the best use of the resulting data. We’ll also review ways to visualize your data and which best suits your needs. Finally, we’ll look at different types of probability distributions, how they’re affected by random variables, and how to combine random variables to form a new distribution.
