Emily is interested in understanding if there is a relationship between whether or not people think the diversity training should be required (yes/no) and whether they attended the recent diversity training in their department (yes/no). Emily constructs a simple questionnaire and sends it to 50 people in her department and gets 50 responses back. What test (s) should Emily use in order to both figure out the strength of the relationship between these variables as well as the generalizablity of her results?
