Great for PsyD doctoral student
I’m a Clinical Psychology doctoral student and I’m taking a doctoral statistics course. However, statistics is in no way intuitive for me and I’ve found this, and the recommended book invaluable. Dr. Fulton even sent the companion powerpoint presentations and StatKey link. I listen (and sometimes re-listen) to this podcast every day on my long drive to practicum residency. It is great! It helps me supplement what I’m learning in class and Oreo are better for classes. I also really appreciate his focus on making it more intuitive and developing the the ability to visualize statistical concepts with greater ease. Thank you!
Statistics Made Simple
I’m 72 and wanted to refresh my knowledge of Statistics. I found the podcast doing a Google search. I’ve finished 14 of the 24 parts and plan to complete it. I may have bitten off more than I can chew. But I’m learning. Thank you for creating this resource.
Great podcast
