How are mean and standard deviation related
Web9 de dez. de 2024 · Once the company has determined the mean, it then needs to use the formula to find the relative standard deviation. The formula is as follows: (S x 100)/x = relative standard deviation. In this problem, S is equal to 5 (the standard deviation) and x is equal to 27 (the mean). So, 5 multiplied by 100 equals 500. 500 divided by 27 equals … Web18 de mai. de 2024 · Big investors and companies apply these terms for the valuation of stock price and future prospectus.
