• QUOTE: A test used to determine the statistical significance of an observation. Two main types of error can occur:
• 1. A type I error occurs when a false negative result is obtained in terms of the null hypothesis by obtaining a false positive measurement.
• 2. A type II error occurs when a false positive result is obtained in terms of the null hypothesis by obtaining a false negative measurement.
• The probability that a statistical test will be positive for a true statistic is sometimes called the test's sensitivity, and the probability that a test will be negative for a negative statistic is sometimes called the specificity. The following table summarizes the names given to the various combinations of the actual state of affairs and observed test results.
• result name
• true positive result sensitivity
• false negative result 1-sensitivity
• true negative result specificity
• false positive result 1-specificity
