Meditation on ICC
Channel: Elizabeth Page-Gould
Date: 2022-12-05

16-minute meditation with 11.5 minutes of initial thoughts on the Intra-Class Correlation Coefficient (ICC). The ICC is both a correlation and a proportion of variance. How? The reflections will be the most meaningful to viewers who are already familiar with the ICC and correlation and are comfortable with comparing equations.

This video is part of a series of meditations on statistical topics that were originally created by Prof. Elizabeth Page-Gould to accompany her graduate course on "advanced statistics" for psychology PhD students at the University of Toronto. However, this video is the first in the series that was not developed to accompany a particular lecture for that class. This statistics meditation was inspired by a series of fun conversations with Joel Le Forestier, a PhD candidate in Dr. Page-Gould’s research lab at the University of Toronto. 💖

Movie editing was done with Apple iMovie. Pixel values for animations were generated with R 4.0.5 (R Core Team, 2021) and R Studio 2022.07.2 and then created and animated using Apple Keynote. The sound was downloaded from freesound.org for a clip from user grimmeisenstrobel (https://freesound.org/people/grimmeisenstrobel/sounds/269247/). Microsoft Stream was used to upload and automatically transcribe the video subtitles prior to uploading it to YouTube.
