WebThe Additive Component If the multiplicative component is set equal to one, the linear transformation becomes X' = a + X, so that the effect of the additive component may be examined. With this transformation, a constant is added to every score. An example additive transformation is shown below: Linear Transformation where a=20, b=1 X X' = a … WebThe standard deviation is a measure of "spread", i.e. how far values vary from the mean. Adding the same fixed number to each output changes the "location" of each data point, but it doesn't change the spread. Multiplying each number by a constant doesn't change the location, but it changes the spread: multiplying by $2$ changes a gap of $7$ to ...
