which statement is the definition of the coefficient of variation? a.the difference between the largest and lowest value of a set of data b. the middle value of a set of data c. a measure of variation when two samples have different units d. the squared value of the standard of deviation
Answers
Answer:
The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage. ... The lower the value of thecoefficient of variation, the more precise the estimate.
D is your answer....
d. The squared value of the standard of deviation
In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution.
The formula for finding the coefficient of variation is given by
Coefficient of variation = Standard Deviation / Mean
It is most likely a decimal number and can be multiplied by 100 to get a percentage.
It is a measure of how much around the mean the data set is dispersed. The greater the value of coefficient, greater the deviation from the mean and vice versa.
