Imagine that your centre or school is looking for an assessment instrument to measure reading ability. The selection has been narrowed to two possibilities: Test A shows measures of strong validity, but there is no information about its reliability; Test B includes measures of strong reliability, but there is no information about its validity. Which test would you recommend? Be sure to include at least three specific reasons as to why you chose the test you did.© BrainMass Inc. brainmass.com October 25, 2018, 9:20 am ad1c9bdddf
Reliability and Validity
1. Both measures are important to any test.
Reliability without validity and vice versa brings significant questions of using any test instruments.
However, in the case provided for you by your professor, a forced situation- I would recommend to choose Test A ...
Choosing tests to administer for reading ability while considering test reliability and validity.
Validity Versus Reliability
Validity is more critical to measurement than reliability. Maybe the validity versus reliability is more context related. In certain situations, you might be more interested in having valid results, such as for a blood sugar (glucose) measurement. That measurement has to be valid otherwise you might under or over dose on insulin which could lead to bigger health issues. But if you are weighing yourself, does it really matter if it's valid as long as the results are reliable and I can tell, relatively speaking, whether I'm getting heavier or lighter?
