Question

An interval scale contains _____.

		mutually exclusive and collectively exhaustive categories as well as the property of order, but not distance or unique origin
		the properties of order, classification, and equal distance between points but no unique origin
		mutually exclusive and collectively exhaustive categories, but without the properties of order, distance, and origin
		the properties of classification, order, equal distance, and unique origin

Answer 1

The correct option is: the properties of order, classification, and equal distance between points but no unique origin

The interval scale is a quantitative measurement scale where there is order, the difference between the two variables is meaningful and equal, and the presence of zero is arbitrary. It measures variables that exist along a common scale at equal intervals. The measures used to calculate the distance between the variables are highly reliable.
