Root Mean Square Or Standard Deviation

Click For Summary
SUMMARY

The discussion focuses on calculating a student's curved grade based on a college test score, average, and root mean square (RMS). The average score was 63, with an RMS of 16, and the student scored 86. The professor's curving method is not explicitly defined, but it is suggested that simply adding a constant to all scores may lead to unrealistic results, such as exceeding 100%. Understanding the specific curving formula is essential for accurate grade calculation.

PREREQUISITES
  • Understanding of root mean square (RMS) calculations
  • Familiarity with grading curves and their implications
  • Basic knowledge of statistical methods
  • Ability to interpret and apply formulas for grade scaling
NEXT STEPS
  • Research the specific grading curve formulas used in educational settings
  • Learn about statistical measures such as mean, median, and standard deviation
  • Explore how to calculate RMS and its applications in grading
  • Investigate methods for scaling grades without exceeding maximum limits
USEFUL FOR

Students, educators, and academic administrators interested in understanding and applying grade curving techniques effectively.

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%.
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
