A measure of central tendency is one value that can represent the total population and acts like the central gravity towards which all the other values move.


Standard deviation - as the name suggests is a measure of the deviation. Deviation means change or distance. But change is always followed by the word 'from'. Hence standard deviation is a measure of change or the distance from a measure of central tendency - which is normally the mean. Hence, standard deviation is different from a measure of central tendency.
