PHCH 667 EXAM 1 TEST QUESTIONS WITH
VERIFIED ANSWERS [ GRADED A+]
accuracy - ✔✔mean, how close to actual value
precision - ✔✔Standard deviation, how close values are to each other
the most important key parameters of a QUALITATIVE test - ✔✔reference values,
predictive values, specificity

, The reference range most acceptable for quantitative tests - ✔✔within 95% of the
mean value
for quantitative tests, critical values typically are considered those that occur
where? - ✔✔so far outside the reference range as to portend mortality
for a qualitative test, sensitivity is determined by - ✔✔TP = TP/(TP + FN)
for a qualitative test, specificity is determined by - ✔✔TN = TN/(TN + FP)
predictive values for a negative qualitative test is best described as: - ✔✔NPV =
TN/(TN + FN)
predictive values for a positive qualitative test is best described as: - ✔✔PPV =
TP/(TP + FP)
