An outline of this training course
An essential skill for anyone working with data is the ability to identify relationships and draw effective conclusions. However, the challenge lies in determining whether those relationships are real or coincidental and how to recognize that uncertainty.
In Introduction to Statistics for Data Analysis I, Dr. Andrew Gard introduced key statistical techniques, focusing on how to implement and apply the appropriate tests when analyzing a single variable. In this course, he builds on those techniques, exploring statistical tools used to determine the relationship between two variables.
Data analysts will often want to answer questions about how multiple variables in a dataset are potentially related to one another, or how samples from different populations are potentially related. Throughout the course, he demonstrates how to utilize the appropriate tool to draw valid conclusions. His practical approach guides you through the process of selecting a test, common pitfalls to avoid, and how you can apply the techniques learned to real-life scenarios.
What are needed to take this course
Participants of this course must have basic knowledge and understanding of variable types, and descriptive and inferential statistics. No other advanced preparation is needed to take this course.
Although the demonstrations in the course are done in R, they are intended to be generalizable to Python or any other statistical software you choose to use. Knowledge of R is not a prerequisite for taking this course.
Who is the course for
Anyone working with data and attempting to draw constructive, generalizable conclusions from data
