The mean is an average that considers every score in the data set. Therefore, any change to the data set will affect its overall value. Adding or removing a score will change the number of scores being averaged, thus affecting the mean. Similarly, changing the value of a score will directly affect the value being used in the computation of the mean, resulting in a change in the overall mean.
