Task 4: As a statistics lecturer, I am always interested in the factors that determine whether a student will do well on a statistics course. Imagine I took 25 students and looked at their degree grades for my statistics course at the end of their first year at university: first, upper second, lower second or third class (see Task 1). I also asked these students what grade they got in their high school maths exams. In the UK, GCSEs are school exams taken at age 16 that are graded A, B, C, D, E or F (an A grade is better than all of the lower grades). The data for this study are in the file grades.sav. Carry out the appropriate analysis to see if GCSE maths grades correlate with first-

year statistics grades. ①
