WebCriterion-related evidence of validity would be provided by: answer choices comparing scores on an instrument with scores on another instrument given to the same sample giving the instrument again at a later time comparing scores on the instrument with those obtained with another sample giving a second instrument to a second sample Question 12 WebFrom the results of this Lawson criterion, there are two ways how to reach economically viable fusion. The first is to keep plasma with relatively low density (n ≈ 10 20 m −3) but for a long time (τ ≈ few seconds). This way leads to magnetic confinement.

A numeric variable can appear multiple times in the data with different cut offs or thresholds. Also final classifications can be repeated. Criterion validity is assessed in two ways: 1. By statistically testinga new measurement technique against an independent criterion or standard to establish concurrent validity 2. By statistically testing against a future performance to establish predictive validity The measure to … See more Criterion validity shows you how well a test correlates with an established standard of comparison called a criterion.
