    Nt1310 Unit 4 Mla

    To get my calculations for the GPAs of the students in the MBA program at Whatsamattu U. I created the ranges from 2.5 -4.0. They were split into 6 different ranges. They were 2.5-2.75, 2.75-3.0, 3.0-3.25, 3.25-3.50, 3.50-3.75, 3.75-4.0. I then counted the frequency of each value. The text states that “the frequency column counts the total occurrences of each value”, Mirabella (2011). I found 0 students in the 2.5-2.75 gpa range, 20 in the 2.75-3.0 range, 47 in the 3.0-3.25 range, 44 in the 3.25-3.5 range, 55 in the 3.5-3.75 range, and 34 in the 3.75-4.0 range. The frequencies added together gave me the total of 200. I know this is correct because that is the same amount of students I have in the sample. I then took the individual frequencies and divided them by the total number of students. This gave me my relative frequency. The relative frequency is the percentage of the students who have the same range in their gpa. As stated before there are no students with a gpa in the range of 2.5-2.75, so the numbers for that range, across the board will be 0. The relative frequency for the gpa range of 2.75-3.0 is 10%, 23.5% for 3.0-3.25, 3.25-3.50…
