I promise I will go back to my series on open-coding, but after the webinar I gave last week I realized there was a big interest in using Studiocode for Inter-rater reliability (IRR). There are several methods for calculating IRR, and the method you choose is dependent on your data type. In this first video I will give detailed instructions on how to calculate IRR for frequency-count data using point-by-point agreement. The video I am coding is another example of a teacher using Discrete trial training with a student. I coded the video for “correct responses” by the student. If this were a research study, and I were drawing conclusions about how this strategy improves a student’s accuracy, I would need to make sure I was accurately coding the student responses by using a second coder as a reliability checker. In this video I explain how I could do this with Studiocode.
