<p>Class: Math 10A
Average: 21/26
Standard Deviation: 4.6</p>
<p>What do you think an A would be...24-26 or 23-26?</p>
<p>My math 10A class gets curves.
These are the test statistics:
Mean: 21 points /26 points as in 80.77 percent right
Standard Deviation: 4.6 points
What do you think would be the range for an A and A-?</p>
<p>My school grades on A,A+, A-, B+,B,B-, C+,C,C-...basically plus-minus system</p>
<p>For fall 2006 this was the grade distribution for the class: Number of people getting the grade/ Letter Grade/ percentage of people getting the grade
27 / A+ / 3.59%
108 / A / 14.34%
75 / A- / 9.96 %
83 / B+ / 11.02%
100 / B / 13.28%
69 / B- / 9.16%
62 / C+ / 8.23%
93 / C / 12.35%
46 / C- / 6.11%
54 / D / 7.17%
36 / F / 4.78%</p>
<p>Total Students: 753</p>
<p>Grading: Your course grade will be determined by your cumulative average at the end of the term and will be based on the following scale:</p>
<p>A+ A A- B+ B B- C+ C C- D
97 93 90 87 83 80 77 73 70 60</p>
<p>We will adjust the scale (curve) to be more lenient, but we guarantee that the grade corresponding to the letter grade will be no lower.</p>
<p>A mean score of 80.77 is pretty high so i wouldnt count on having any curve.</p>
<p>Most professors try to have the mean grade correspond to a C+/B-. The mean grade for your midterm is already a B-. That probably means no curve. </p>
<p>As a general rule, one standard deviation away from the mean will give you an A. In this case:
Mean = 21
SD = 4.6
21 + 4.6 = 25.6
That's really high (higher than without a curve) which is once again, why I doubt that there will be a curve. But really, ask your professor or TA if you're really that desperate to know.</p>
<p>I should mention that this isn't like high school. You can't go to your professor and ask what your grade is. They don't know either. The curve right now and the curve at the end of the class might be completely different. Maybe the average for the first midterm is 50%, but for the final it's 80%. Maybe it's the other way around. They can't predict anything. The best you can do is look at the means for midterms and see whether you're close to the A range or not. You can usually tell.</p>
