In chance principle and statistics, the coefficient of variation (CV), also referred to as relative normal deviation (RSD), is a standardized measure of dispersion of a chance distribution or frequency distribution.
Relative Commonplace Deviation, RSD is outlined and given by the next chance operate:
The place −
- = the pattern normal deviation
- = pattern imply
Discover the RSD for the next set of numbers: 49, 51.3, 52.7, 55.Eight and the usual deviation are 2.8437065.
Step 1 – Commonplace deviation of pattern: 2.8437065 (or 2.84 rounded to 2 decimal locations).
Step 2 – Multiply Step 1 by 100. Set this quantity apart for a second.
Step 3 – Discover the pattern imply,. The pattern imply is:
Step 4Divide Step 2 by absolutely the worth of Step 3.
The RSD is:
Be aware that the RSD is expressed as a proportion.
