Instructor Michael Cleveland

Michael Cleveland is an associate professor of human development at Washington State University. His research focuses on factors that increase the risk of relapse among people with substance use and addiction, with the goal to provide “in-the-moment” interventions that help people manage the stress, anxiety, and other relapse “triggers” that accompany the recovery process. His quantitative expertise centers on the appropriate application of modern statistical techniques to answer complex research questions.

  • What level of statistical training is required for the course?

    This course is for learners with a foundational knowledge of regression analysis. Prior experience with SAS is not required.

  • There is no way that I will be able to set aside the four days required to take this course. Is the timing flexible?

    Since this is an on-demand course, the timing is entirely up to you. Once you enroll and the course has launched, you will have unlimited access to the content. You are free to pause and return to your lessons as needed.

  • Will you give me feedback on my analyses?

    Unfortunately, personal feedback is not possible given the volume of researchers we serve. We are certain that Dr. Cleveland's thorough approach to guiding you through every step of using SAS, successfully perform MLM techniques with your own data. Note that we here at QuantFish are always happy to help you navigate any technical issues related to the course itself.
