Quizplus · Accepted Answer

The standard deviation is the square root of the variance and is expressed in the same units as the data. The range is the difference between the maximum and minimum values and is not related to variance. The standard error is a measure of the variability of the sample mean, and is not the same as the standard deviation. The mean is the average value of the data, but it is not a measure of variability. Statistical significance is a measure of whether the results of a study are likely to have occurred by chance, and is not related to variance.
