When the relationship between the unit of measurement of a scale (strength)and an outcome (pounds lifted)can be described by a linear equation Y = a + bX,the scale is said to have what property?
A) magnitude
B) equal intervals
C) absolute zero
D) nominal

Question

Quizplus · Accepted Answer

The property described is equal intervals, which means that the difference between any two values on the scale is the same throughout the range. This is reflected in the linear equation form Y = a + bX, where b represents the constant rate of change or slope of the line.
