Hey all, I'm new to this forum and have a question I hope you guys can help me with. Some background on my math knowledge: I took pre-Algebra in 8th grade, Analysis I 9th, Analysis II 10th, Calculus 11th, Statistics 12th. (Yea, apparently I tested out of Algebra I-II but since I never took it, there is a lot that I never learned properly) I am now three years into college and have only taken college level statistics. In HS I was pretty good at math, now I'm very much out of practice. I am not entirely sure which forum I should put this on so Moderators feel free to move it. My conundrum: I'm currently in a nursing program and this question has to do with the way my school grades us for the semester (hang on with me, this does have to do with fairly difficult math, specifically graphing, let me explain) Alright so this semester is split in half, and there are two units to take (each with three x 50 question tests), there are also two sections. Unit A = Respiratory and Cardiac Unit B = Gastrointestinal and Genitourinary Section 001 takes unit A first, then unit B. Section 002 takes unit B first, then unit A. There is also a final test (HESI) that is worth 20% into whatever unit you take last. We receive two final grades (that go onto the transcript and determine progression in the program), one for Unit A, one for unit B. The grading breakdown looks like this: Section 001 - Grade #1 = 100% Unit A grade. Grade #2 = 80% Unit B grade + 20% HESI Section 002 - Grade #1 = 100% Unit B grade. Grade #2 = 80% Unit A grade + 20% HESI The overall passing grade for each final grade is 74.5. I realized today that two individuals could score the same in both units and on the test, but be in different sections, and one could pass, and one could fail. For instance: Unit A grade = 90% Unit B grade = 80% HESI = 50% Section 001 student Grade #1 = Unit A grade = 90% Pass Grade #2 = Unit Bx0.8 + HESIx0.2 = 80x0.8 + 50x0.2 = 64x10 = 74% = Fail This student has to wait a year before (s)he can retake the failed class. Section 002 student Grade #1 = Unit B grade = 80% Pass Grade #2 = Unit Ax0.8 + HESIx0.2 = 90x0.8 + 50x0.2 = 72+10 = 82% = Pass This student progresses as normal. As you can see, with the same grades on all tests, just taken in a different order, one would pass and one would fail. Not exactly fair. This is my question: The proof proves that this could be an issue in some cases, and I want to quantify the incidence of that issue. Is there a way to plot these values on a graph (three dimensional maybe? maybe more than one graph? I'm really not sure) To show when the section difference matters and where it doesn't? Some parameters would be: Unit A grade = a number between 0-100 at intervals of 0.6(repeating) Unit B grade = a number between 0-100 at intervals of 0.6(repeating) HESI = a number between 0-100 at intervals of 2 I messed around with an online graphing calculator and am at a loss. I hope that makes enough sense for you all to understand. If you need any clarification let me know. I'm planning on compiling the information and presenting it to the Dean, hopefully we can get a policy change to split the HESI 10% to each section.
