<p>Let's say you get an 83 on a prelim and the mean for the prelim is a 69 with a standard deviation of 12. If the median grade for the class is a B, would 83 be an A or A-?</p>
<p>More than likely an A, although it depends on the professor/course.</p>
<p>like he said it depends on the course. for most science courses, ie orgo, it would probably be A for that exam. But don’t forget that people drop courses a lot!! and that would raise the mean of the exam so your grade would most likely go below 1 SD. I know for orgo a bunch of people had like <10 for grade/100, so they dropped the mean, but some of them dropped and the mean went up. its the final mean that they grade you on</p>
<p>how do you find out what the mean and the standard deviation is for a prelim and also the median grade for the class?</p>
<p>The mean and standard dev. for a prelim should be given to you by your professor/TA. However, it is at their discretion, so if they don’t want to tell you, that’s their prerogative.</p>
<p>The median grade for a course is given in the median grade reports [Cornell</a> University Registrar: Median Grades](<a href=“http://registrar.sas.cornell.edu/Student/mediangradesA.html]Cornell”>http://registrar.sas.cornell.edu/Student/mediangradesA.html)</p>
<p>How about this?</p>
<p>Say I got an 83 on a prelim, mean was 77% and a S.D. of 12%…what would that be…also the median grade of the class is a B-.</p>
<p>Bio 1101? 10char</p>
<p>the OP has got to be in orgo…impressive grade! :)</p>
<p>bio 101 isnt curved but it did have the same mean and standard deviation</p>
