What is the score that falls exactly in the centre of a distribution of scores,such that half the scores fall below that score and half the scores fall above it

A)  median 
B)  mean 
C)  standard deviation 
D)  mode

The median is the score that falls exactly in the centre of a distribution of scores, such that half the scores fall below that score and half the scores fall above it. It is different from the mean and the mode, which are other measures of central tendency. The standard deviation, on the other hand, is a measure of variability and not central tendency.
