Homework Help: Root Mean Square Or Standard Deviation

  1. Jun 17, 2013 #1
    Hello, I've been trying to find online where I could calculate my grade based off a college curve. So the average grade on the test was a 63. The RMS is 16. I got a 86. So what will my grade curve to? This is out of 50 people. Also, the professor curves to a 70 (I think).

    You would need to know the formula/method the professor uses to scale the marks. Just adding a constant to everything will likely not work, as it can produce some marks > 100%.
