Calculate stats from multiple csv files

I work for a University in Michigan. We are starting to use a software title to deliver and administer tests/surveys. After the test is done the program will write 2 types of files; 1 is an html of all the computer names and their total score, the other is an individual .csv file which details Question number, Question Title, Total Points, and Points Scored. Is there a way to automate the creation of a document that uses all the .csv files to create stats?

Example:
(Suppose that each person has their own .csv file with this info)
Person 1
Question 1: 0 points
Question 2: 1 point

Person 2
Question 1: 1 point
Question 2: 1 point

I am looking for a way to output that 50% of the people got Question 1 right, and 100% of the people got Question 2 right. Assuming that each question will be worth 1 point.

Attached are 2 of the .csv files that the program spits out when the test is completed. Also please ignore that the first question was worth 4 points, in the future it should 1 point or 0 points.

Please let me know if what I am asking is possible.

Thanks
