Read the scenario to answer questions:

1) What is the Dependent Variable? What is its scale of measurement? 

A researcher wanted to examine whether modality impacts ability to learn how to write letters of the alphabet. Children were randomly assigned to one of two groups: one group was taught to trace letters using pen and paper. The second group was taught by using their finger to trace letters on an iPad. After being taught one of these methods for two modules, the researcher then counted the number of correctly written letters of the alphabet for each child.

2) Is this a between-subjects or within-subjects design?

3) If the data violated many of the assumptions for a parametric test, what would be the most appropriate nonparametric statistical test? What would be the most appropriate graph?
