Question

Quizplus · Accepted Answer

A correlation is a statistical measure that shows how two variables are related, and a synchronous pattern of variation between two variables is a way to describe this relationship. Variance refers to the spread of data and is not specific to the relationship between two variables. Power deviation is not a commonly used term in statistics. An operational definition is a definition of a variable or concept in terms of the procedures or operations used to measure or manipulate it, and is not specific to the pattern of variation between two variables.
