Statistical Fundamentals: A Visual Approach Workshop Series—Visualizing Samples with Boxplots and Kick the Bar Chart Habit

Library Building (LIB) 3287 University Way, Kelowna, BC, Canada

This session will address the advantages of box plots over bar charts for displaying the spread and variability in data. Participants will learn how box plots can be used to compare multiple samples, the impact of sample size on data representation, and the efficient identification of outliers.

By the end of the session, participants should be able to create and interpret box plots, appreciate their usefulness in comparing multiple samples, understand the implications of sample size, and identify outliers and median confidence intervals through notches in box plots.

Fitting Models to Data Not Data to Models Workshop Series: (Hierarchical) Generalized Linear Models

Library Building (LIB) 3287 University Way, Kelowna, BC, Canada

This workshop will introduce Generalized Linear Models (GLMs), which allow one to model non-Gaussian (i.e., non-normal) data.

By the end of this session, participants will be familiar with the three parts of GLMs (family of distribution, linear predictor, and link function) and will be able to decide what family of distributions and link function to choose for their data. They will also be able to interpret the output of the summary() function and diagnostic plots for (H)GLMs and recognize the limitations of (H)GLMs.

Statistical Fundamentals: A Visual Approach Workshop Series—All About T-tests and Visualizations

Library Building (LIB) 3287 University Way, Kelowna, BC, Canada

This session will introduce participants to the various types of t-tests, including one-sample, two-sample, paired, and one-sided tests. Attendees will learn about the appropriate applications for each type and the visualization techniques that can enhance the interpretation of t-test results.

By the end of the session, participants should be able to apply and visually represent different t-tests, interpret their results, understand the implications of multiple testing corrections, and select the appropriate test for their data.

Fitting Models to Data Not Data to Models Workshop Series: Generalized Additive Models

Library Building (LIB) 3287 University Way, Kelowna, BC, Canada

This workshop will introduce Generalized Additive Models (GAMs), which allow one to fit models that are complex and nonlinear but easily interpretable, unlike many “black-box” machine learning models.

By the end of this session, participants will be able to fit GAMs in R using the mgcv package and understand the advantages of GAMs over GLMs and LMs.

Statistical Fundamentals: A Visual Approach Workshop Series—Non-parametric Tests and Visualizations

Library Building (LIB) 3287 University Way, Kelowna, BC, Canada

This session will introduce participants to non-parametric tests, which are useful when data distributions do not meet the assumptions of parametric tests. Attendees will learn to compare the adaptability of these tests with different data distributions and to visualize their operation.

By the end of the session, participants should be able to choose and apply the appropriate non-parametric tests for their data, visualize the operation of these tests, and understand the challenges of multiple testing with non-parametric methods.
