Question

29) You are developing a new screen for heart disease which is found to correlate (r=0.7) with the “gold standard” blood test for cardiac enzymes. This is an indication of:

validity from factor analysis

convergent validity

validity from contrasting groups

divergent validity

27) If your sample size is small you:

have a greater chance of type II error

may find a statistical difference that really isn’t there

have a greater chance of type I error

are able to draw conclusions regarding your data easier

Explanation / Answer

29. By definition, Convergent validity is examined by comparing a newer instrument with an existing instrument that measures the same concept or costruct. The validity of both instruments is strengthened when the values obtained from the two instruments have a moderate to strong positive relationship. (Statistics for Nursing Research - E-Book: A Workbook for Evidence-Based Practice By Susan K. Grove, Daisha J. Cipher)

So in this case, 2nd option is correct, Convergent validity

27. If your sample size is small you: have a greater chance of type II error
