A student was interested in whether there was a positive relationship between the time spent doing an essay and the mark received. He got 45 of his friends and timed how long they spent writing an essay (hours) and the percentage they got in the essay (essay). He also translated these grades into their degree classifications (grade): first, upper second, lower second and third class. Using the data in the file EssayMarks.sav find out what the relationship was between the time spent doing an essay and the even- tual mark in terms of percentage and degree class (draw a scatterplot too!).
