Two Miscalculated Effect Sizes That Aren't Standard Errors

In today’s episode, Greg and Eric discuss a new study reporting that 85% of highly cited meta-analyses in the field of strength and conditioning research contain at least one statistical error. The conversation covers common meta-analysis errors, how to spot them, and how to critically interpret meta-analyses. After that, Eric presents a segment on motivation and behavior change. He begins by reviewing evidence-based goal setting strategies, then discusses how we can leverage self-determination theory to get motivated to pursue our goals, and how we can lean on the COM-B (capability, opportunity, motivation, behavior) model to change behaviors in accordance with our goals. This leads to a unified, comprehensive, evidence-based model that covers goal setting, motivation, and behavior change from start to finish.
