Standard Deviation Calculator
As such, the "corrected sample standard deviation" is the most commonly used estimator for population standard deviation, and is generally referred to as simply the "sample standard deviation." It is a much better estimate than its uncorrected version, but still has a significant bias for small sample sizes (N<10). Refer to the "Population Standard Deviation" section for an example of how to work with summations.

How to calculate average Standard Deviation ?
You're looking for the pooled variance: https://en.wikipedia.org/wiki/Pooled_variance Pooled variance is a weighted average of each variance, weighted by the degrees of freedom (n-1) of each set. Once you have the pooled variance, you can take the square root to get the pooled standard deviation. Say you have two data sets: n_1 = 10; mean_1 = 15; sd_1 = 3 n_2 = 15; mean_2 = 12; sd_2 = 2 Then the pooled variance would be: sd_p2 = ( (10-1)*32 + (15-1)*22 ) / (10+15-2) sd_p2 = 5.956521739 And then take the square root to get the pooled standard deviation: sd_p = 2.440598644 Notice that the pooled standard deviation is closer to the second set, because the second set is bigger. Also notice that the mean doesn't factor into the calculation. More on reddit.com

December 21, 2023How do you use standard deviation to calculate how well you need to do?
Assuming that your professors are using standard curve grading practices, I believe we can assume that the final distribution will be approximately normal. This means we can simply calculate the z-score for the 75th percentile which comes out to around 0.674 standard deviations above the mean. We can also put an upper bound on the pre-curved distribution using Cantelli's Inequality to show that the upper bound is 1.732 standard deviations above the mean. Please note that the z-score I calculated is based on the post-curve distribution, which is probably not the same as the one that your class is based on right now. There isn't enough information in this post to determine whether it is possible to get an A based on your scores right now. More on reddit.com

Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a dataset. It indicates how much individual data points differ from the mean (average) of the dataset. A smaller standard deviation means the data points are closer to the mean, while a larger standard deviation indicates greater variability or spread.
