I have scored student’s solutions according to a rubric which is scaled from 1-5. This accounts for the dependent variable. After videoing student’s interactions in groups, I have coded the number of times they said four specific words I was interested in (it was a little more complicated than this, but for the sake of understanding). These four factors account for the independent variables. There are 27 samples in the data which include the student’s scored argument and the number of times they said each of the four specific words. I am hoping to discover if there is a significant positive or negative correlation between their scored argument and the number of times they said each of the four words. Is there a statistical test for this? I have tried Spearman’s rank correlation, but by my understanding I can only use one independent variable for this test. I have included my data below.
