Fundamentals of Statistics I: Exploratory Data Analysis

This is the first workshop in a 5-part series focused on the fundamentals of statistics.

Exploratory Data Analysis (EDA) is essential for understanding your data and a necessary step prior to any testing or modeling. You will learn insightful graphical and numerical techniques for investigating important aspects of your data such as relationships between variables and unusual observations. More specifically you will learn about:

• exploring categorical data using contingency tables and side-by-side bar charts
• exploring numerical data using histograms, box plots, density plots, scatterplots and 3 variable plots
• various useful measures of center, spread and shape for describing data and how to choose between them
• identifying and handling outliers

More on this series

This webinar series was made possible via joint collaboration between Applied Statistics and Data Science Group and Graduate Pathways for Success Program, funded by the Graduate Pathways for Success Program.
Statistics is a scientific discipline that enables reaching meaningful conclusions from data. To produce reliable results, you need to justify the choice of the applied statistical methods and models as well as validate the underlying assumptions.
This webinar series provides an overview of foundational statistical concepts using examples of various data structures. We will discuss types of study designs, methods, models and appropriate application of statistical tests along with interpretations of the results obtained from different statistical tools. The aim is to equip the attendees with a deeper understanding of the key concepts of statistical methodology, rather than solving specific project problems or providing hands-on guidance.
Each webinar is a self-contained introduction to different statistical concepts, but as topics become increasingly complex with each consecutive webinar, some aspects will be built on concepts taught in the previous sessions. Hence, there is benefit in attending all the webinars. If you are a graduate student and have questions about your specific project, please see here for the SOS Program to book a one-hour free statistical consultation
