Answer:
B. When comparing variation in samples with very different means, it is good practice to compare the two sample standard deviations.
Step-by-step explanation:
It cannot be option A because when calculating the standard deviation because whenever you square something you get a non-negative number so this is a property of standard deviation.
It cannot be C because you are using the units of the original data to calculate the standard deviation.
It cannot be D because the standard deviation is a measure of variation of all the data from the mean.
Option B is correct because comparing variation in samples with very different means is not a property of standard deviation.
What is a standard deviation?
It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.
A. It is incorrect when calculating the standard deviation whenever you square something you get a non-negative number so it is the property of standard deviation. It is a property of the standard deviation.
B. It is correct because when comparing variation in samples with very different means, it is good practice to compare the two sample standard deviations. It is not a property of the standard deviation.
C. It is incorrect because you are using the units of original data to calculate the standard deviation. It is a property of the standard deviation.
D. It is incorrect because The standard deviation is a measure of the variation of all data values from the mean. It is a property of the standard deviation.
Thus, Option B is correct.
