Ability of a measurement to give the same result or a similar result with repeated measurements of the same factor

• A. Accuracy

• B. Precision

• C. Reliability

• D. Both A and B

• E. Both B and C

It pertains to the ability of a measurement to be correct on the average

• A. Accuracy

• B. Reproducibility

• C. Reliability

• D. Both A and B

• E. Both B and C

In the “old tuberculin” test, there is a cross reactivity between atypical mycobacteria and mycobacterium tuberculosis. Results yield from an atypical mycobacteria is described to be:

• False-Positive which is a Type I error

• False-Negative which is a Type I error

• False-Positive which is a Type II error

• False-Negative which Type II error

When a test falsely indicates the presence of disease in no diseased subjects then-

• The test is not sensitive

• The test is not specific

The ability of the test to identify the absence of a disease or illness correctly

• Specificity

• Sensitivity

• Reproducibility

• Reliability

The ability of the test to identify the presence of a disease or illness correctly.

• Specificity

• Sensitivity

• Reproducibility

• Reliability

When the test’s specificity is high, it is more likely to give a true negative result and correctly identify that the disease or illness is not present.

• TRUE

• FALSE

Sensitivity values are associated with ________ and __________.

• True positive and False Negative

• False positive and True negative

• False positive and False negative

• True negative and True positive

Specificity values are associated with _________and __________.

• True positive and False negative

• False positive and True negative

• True negative and False positive

• False negative and True positive

When the test’s sensitivity is low, it is more likely to give a true positive result and correctly detect the disease or illness when it is present

• TRUE

• FALSE
