# Introduction to Statistical Concepts III: Two group comparison and ANOVA

#### Date & Time

Thursday, 25 November 2021
13:00 to 15:00

Online

#### Offered by

Graduate Pathways to Success and The Applied Statistics and Data Science Group (ASDa)

#### Registration Closed / Past Event

In this webinar, you will learn how to gain insight from a random and unbiased data sample of a population:

• population distribution vs sample mean distribution
• hypothesis testing
• statistical significance
• t-test for comparing two groups and its assumptions
• non-parametric alternatives to t-test and when to use them
• one-way and two-way ANOVA for comparing more than two groups

Check out the video below for a teaser from a previous session:

This is the third workshop in a 6-part series focused on the foundations of statistics.

##### More on this series

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 (https://asda.stat.ubc.ca/sos/) to book a one-hour free statistical consultation.

The Applied Statistics and Data Science Group (ASDa) in the UBC Department of Statistics provides assistance in the statistical formulation of research questions, the design of experiments and sampling plans for surveys, the choice and explanation of statistical methodology, statistical computing and graphics, statistical analysis, the interpretation of findings, and more. ASDa also plays a role in continuing education on and off the UBC campus, giving seminars and workshops on statistical concepts and methodology to various departments, research groups and at teaching hospitals.

#### Facilitator

Nikolas Krstic is a PhD student at the Department of Statistics and a part-time Statistical Consultant with ASDa. While pursuing his previous degrees, he worked as a statistical analyst at the British Columbia Centre for Disease Control (BCCDC), authoring several published papers on a wide range of environmental health topics. Over the past couple of years, he has worked with numerous clients on projects from a variety of different disciplines. During his studies, research and consulting work, he has developed a strong background in regression analysis, spatial statistics and statistical learning.
