Coefficient of Variation The coefficient of variation standardizes a variable's dispersion (standard deviation) relative to its mean. Imagine two variables, each with a standard deviation of 20. If Variable 1 has a mean of 100 and Variable 2 has a mean of 10, it is obvious that has more relative uncertainty. The coefficient of variation, the amount of risk per unit of the mean, is found by dividing the standard deviation by the mean, as follows: CV = Standard Deviation...
This data is from a sample. Calculate the mean, standard deviation, and coefficient of variation. 49.1 41.2 21.9 40.5 17.5 35.2 30.3 Please show the following answers to 2 decimal places. Mean - Standard Deviation - Coefficient of Variation % (Please enter a whole number.)
The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude?

She finds that the sample standard deviation is $3325. Assume the sample is taken from...
Find the range, variance, and standard deviation for the given sample data, if possible. If the measures of variation can be obtained for these values, do the results make sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of poas.

In Exercises 5-20, find the range, variance, and standard deviation for the given sample data. Include appropriate units (such as "minutes") in your results. (The same data were used in Section 3-2 where we found measures of center. Here we find measures of variation.) Then answer the given questions.
