20. What is the biggest advantage of the standard deviation over the variance? a) The standard deviation is always smaller than the variance. b) The standard deviation is calculated with the median instead of the mean. c) The standard deviation is better for describing skewed distributions. d) The standard deviation is in the same units as the ...

Using the standard deviation as a unit of measurement, find out of how much smaller or taller than the mean the each of remaining members of the class are - after all the standard deviation is a deviation like all the others, only it is Standard, which means it is the typical, or it is the expected normal deviation …

=STDEVP(range) gives (, the population standard deviation =STDEV(range) gives s, the sample standard deviation. We use standard deviation more often than variance because the standard deviation of a set of data is measured in the same units as the data itself.

Mar 15, 2013 · This is defined as the variance of the original numbers, and the standard deviation is its positive square root, or 2. Taking the square root returns us to a value of the same order of magnitude as our original readings. So a traditional analysis would show that these ten numbers have a mean of 10 and a standard deviation of 2.

The standard deviation is the average variation of the data values from the mean of the values. The standard deviation is found by taking the square root of the variance, and the standard deviation is more useful than the variance in reporting results so it is the measure that is typically reported.

The extended estimate is always better than the Hozo et al. [1] estimate, in both bias and standard deviation. With samples of size 100, the extended estimate gives bias 21.3 or 13% in the mean ...

Why is standard deviation more significant than variance? - Quora
Why is standard deviation a better measurement of data variation than the range? Standard deviation uses the entire data, while the range uses only the two extreme values. Therefore, range is sensitive not only to the outliers but less stable than standard deviation.
