Quizplus · Accepted Answer

The standard deviation is a measure of variability or dispersion of data from the mean. The median is a measure of central tendency and does not reflect variability. The normal distribution is a type of probability distribution in which the data is distributed symmetrically around the mean, but it is not a measure of variability. The correlation coefficient measures the strength and direction of the relationship between two variables, it is also not a measure of variability.
