C)Comparative scale.
D)Stapel scale.

Question 18

A nominal scale is always dichotomous.

A formative scale is used when a construct is viewed as an explanatory combination of its indicators.

Question 23

Concurrent validity is a form of construct validity.

Question 24

Question 29

Construct validity is the extent to which experts are of the opinion that an instrument measures what it is intended to measure.

Question 30

While it makes sense to test the inter-item consistency of reflective scales,it does not make sense to test the inter-item consistency of formative scales.
