31.  Sensitivity is the ability of a test to detect a positive result in those with a disease or condition  Specificity is the ability of a test to detect a negative result in those without a disease or condition

32.  Positive Predictive Value (PPV) is the likelihood that when a test is positive, the patient has the disease/ condition

33.  Negative Predictive Value (NPV) is the likelihood that when a test is positive, the patient has the disease/ condition

34.  The P-value is the probability that a finding is due to chance  When the P-value is less than 0.05 (5%), scientists call that “statistically significant”

35.  Statistical significance is when a finding is unlikely to be due to chance
