Detailed explanation-1: -Standard deviation is a measure of central tendency.
Detailed explanation-2: -Standard deviation is the other measure of variability we will use in this course. It expresses the variability in terms of a typical deviation in the data set. This will be a single number that gives us the distance of typical scores in the dataset from the mean.
Detailed explanation-3: -Standard error and standard deviation are both measures of variability. The standard deviation reflects variability within a sample, while the standard error estimates the variability across samples of a population.
Detailed explanation-4: -A measure of central tendency is one value that can represent the total population and act like the central gravity towards which all the other values move. Explanation: Standard deviation-as the name suggest is a measure of the deviation. Deviation means change or distance.
