If the test/retest reliability of a measure is .80, it means The measure meets typical reliability standards. The measure should be revised to get closer to 100% reliability The measure is actually unreliable and should be discarded The measure likely has good construct validity

Group variability, scoring reliability, test length and item difficulty all affect test score reliability; discuss how each of these variables impact test design and how you might mitigate those impacts.

Consider an expensive part with a reliability of 89.8%. If the part failed is will cost the firm $4200.  On each part, a backup can be installed that costs $280. What is the minimum allowable reliability for the backup that would make installing it worthwhile?

When observations can be placed into oneof two categories. Examples include items(observations) that can be classified asa. Good or badb. Pass or failc. Operate or don’t operate

You have conducted a zone of tolerance analysis for your local pizzarestaurant. You find that the lengths of the reliability andresponsiveness boxes are much greater than those of the other threeservice quality dimensions. You also find that the restaurant ispositioned above the zone box on reliability but below the box onresponsiveness. What should you tell the manager to do?

If the RDF is equal to 0.2, then the Reliability is Group of answer choices 1 + RDF 1 - RDF b & c 0.2 0.8

Assessing how well a product or service performs its intended purpose is the definition of the value dimension quality. true or false

consider the following reliability analysis for the  variable customer difference. What could you conclude from it?

Why is it that testing can only determine whether or not mistakes have been made, but not whether or not mistakes have not been made?

The reliability dimension of quality relates to the useful life of a good or service.  True  False
