WWC Online Training, Module 3: Equivalence, Part 1

Module 3 of the What Works Clearinghouse (WWC) Group Design Standards Training focuses on the WWC baseline equivalence standard, which the WWC applies to studies that use randomized controlled trials (RCTs) with high attrition or compromised random assignment and those that use quasi-experimental designs (QEDs). This module describes how the WWC defines baseline equivalence, how to assess equivalence, as well as when and how to apply the WWC’s equivalence standard. This module also covers how the WWC determines the characteristics that it uses to assess baseline equivalence. Chapter 1 introduces Module 3.
