Numbers in the data set that fall within one standard deviation of the mean are part of the data set. So, I disagree with some of the answers given here - standard deviation isn't just an alternative to mean deviation which вЂ¦ In some cases, people prefer to put the descriptive statistics in parentheses.

spread of scores) is a In other words, the standard deviation is a term that arises out of independent random variables being summed together. the paired t- test for comparison of strongly dependent sets of data. the Cochran variant of the t-test when the standard deviations of the independent sets differ significantly 3. The standard deviations of both teams are (8.3) and (7.9) respectively. A standard score represents the number of standard deviations above or below the mean that a specific observation falls. If a collection of random variables is not independent, it is dependent. Standard deviation is expressed in the same units as the original values (e.g., minutes or meters). ThatвЂ™s a plausibility argument that the standard deviations of the sum, and the difference should be the same, too. I'm going to try for a slightly simpler approach, hopefully to add some context for those who are not as well versed in math/stats.

Data stored in dataset variables include both raw (as originally collected) and derived values (e.g., converted into standard units, or computed on the basis of multiple values, such as an average). Consequently, if we know the mean and standard deviation of a set of observations, we can obtain some useful information by simple arithmetic.

If means and standard deviations were not reported, we used the procedures of the Comprehensive Meta-Analysis software (version 2.2.021) to calculate the effect size using dichotomous outcomes and if these were not available either, we used other statistics (such a t-value or p-value).
