Adding the same constant to each score in a distribution (or subtracting the same constant from it)will

Quizplus · Accepted Answer

When the same constant is added to each score in a distribution or subtracted from it, it will shift the distribution to the right or left, respectively. This will change the location of the mean by the same amount as the constant added or subtracted. For example, if we add 5 to each score in a distribution with a mean of 70, the new mean will be 75. Therefore, the mean will change by that constant.
