Number of Absences and Missed Assignments for Six Students For example, suppose a statistics teacher had records of absences (X 1) and number of missed homework assignments (X 2) during a semester for six students (N=6). A linear transformation is useful in that it is cognitively simpler to deal with a single number, the transformed score, than it is to deal with many numbers individually.
Where K is the number of different scores for each subject and X' is the linear combination of all the scores for a given individual.Ī linear transformation combines a number of scores into a single score. In its most general form, a linear transformation appears as follows: A linear transformation is a weighted combination of scores where each scores is first multiplied by a constant and then the products are summed. Most multivariate statistical methods are built on the foundation of linear transformations.
