I am studying the effects of Digital Storytelling on students’ digital literacy. At the end of each unit, students will have created digital stories, which will be assessed using a rubric designed to look at the components of the digital literacy.

So, at the end of study, I will have four sets of scores. Does it make statistical sense for me to use Friedman’s test to look at whether there is a significant difference across four units and then make conclusion accordingly?
