I've finished the coding for means of interest, knowledge, and employablity of Theology and Religious Studies by the other subjects. I've installed the required packages for making a graph of the Likert responses (categorical to go along with the already created means ones), but have not been able to figure how it works yet. I'll have another look at it later and work with it more.
I have put only the complete participants' data into a new .csv file in order to upload to R and begin analyses so some can be done for next week. I have made new, in some cases slightly shorter, variable title names at the top of the .csv for ease of titling and analysing.
