Statistical Solutions Inc. is celebrating its first anniversary with a 5-hour hands-on workshop! This workshop is designed to introduce the RStudio statistical environment to those who are looking to use R for applied statistical tasks. Topics include data coding and management, as well as how to perform descriptive, bivariate and multivariate analyses.





This 5 hour hands-on workshop will be taught by Mariola Moeyaert, Ph.D. through Zoom. No prior knowledge of RStudio is assumed.

I am pleased to organize a free webinar on the design-comparable effect size (D-CES) for single-case design (SCD) studies. This webinar is intended primarily for researchers and applied analysts interested in quantifying SCD intervention effectiveness.

The webinar will cover the following topics:

  • Introduction to SCD and D-CES

  • Appropriate use of D-CES in the context of the WWC

  • Advantages and disadvantages of D-CES relative to other effect sizes appropriate for SCDs

  • Use of the web-based shiny application scdhlm to calculate D-CES

  • Walkthrough of calculating and interpreting the D-CES with example data

This 2-day meta-analysis workshop provides hands-on exposure to the process involved in conducting a meta-analysis from the planning stage, through the selection of appropriate statistical techniques, through the issues involved in analyzing data, to the interpretation of results. Examples and case studies from the social sciences will be integrated into the discussions and lectures. Day 1 and day 2 of the workshop are designed independently, which allows participants to sign up for one or multiple days depending on their interest and level of experience.
