For this exercise I selected 12 biostatistics students (from previous cohorts) and I ranked them from 1 to 12 based on their participation in the class, with 1 being and lowest and 12 the highest. This ranking was then compared with the actual grades of the students ( 98 being the best grade and 61 being the worst grade.). My hypothesis was that the higher I ranked the student (i.e. the more the student participates in the class) , the better the final grade.

Follow the steps for hypothesis testing, conduct the statistical analysis using SPSS and write the results
