This is my very first time using R to analyze my research data. It's a psychology study, and we used 10 different scales to measure our variables.
I finally organized the data frame sufficiently to analyze it, but now I realize I can't quite find how to average my scores.
For example, I have 80 rows (participants), and one scale is 20 items.
All the odd columns are variable A and all the even columns are variable B.
I need to have an average variable score for each participant, is there a way to do that?
Any help is appreciated, I'm feeling pretty lost
