Join the What Works Clearinghouse (WWC) for a webinar on the effect size and standard error formulas that are new to Version 4.1 of the WWC Standards Handbook and the WWC Procedures Handbook, including those in the 4.1 supplement to the WWC Procedures Handbook. This webinar is intended primarily for current WWC reviewers who are certified in the WWC group design standards and conduct reviews in the online study review guide (OSRG). The webinar may also appeal to researchers who conduct quantitative meta-analyses in education and related social/behavioral sciences, as some of the featured standard error formulas will be new to those in the meta-analytic research community.
The webinar will cover the following topics:
• Importance of effect sizes and standards error in version 4.1 of the WWC Standards and Procedures
• Formulas for individual-level assignment studies
• Formulas for cluster-level assignment studies
• Practical guidance for study reviewers
If you are not able to attend, sign up to be notified when the webinar recording and transcript are available.
The webinar will take place on Wednesday, December 2 from 2:00-3:00 p.m. Eastern Time.
