RMS stands for root square mean.
Root Mean Square, or quadratic mean, is a statistical function for finding the average of a series even if it contains negative numbers.
Formula to calculate RMS.
- Begin by squaring the number and add them together.
- Then divide the sum of the squares by the number of observations(n).
- And find the square root of the result.
Example:
Find the RMS of the student’s age as stated below.
12 years, 13 years, 12 years and 14 years.
n = 4
Therefore, your RMS is 12.78.
