Quizplus · Accepted Answer

When a scale has the property that the relationship between its unit of measurement and an outcome can be described by a linear equation (Y = a + bX), it is said to have equal intervals. This means that the difference between any two adjacent values on the scale is consistent throughout the scale, which is a characteristic of a linear relationship.
