Comparing the accuracy of two binary diagnostic tests

Compare the sensitivity and specificity of two diagnostic tests and make inferences about the differences.

You must have already completed the task:
  1. Activate the analysis report worksheet.
  2. On the Analyse-it ribbon tab, in the Diagnostic Accuracy group, click Test Equality.
    The analysis task pane Comparisons panel opens.
  3. In the Test drop-down list, select the statistical test to perform.
    The tests available depend on whether the samples are paired or independent. It is important to ensure you have set the model correctly using the Model drop-down menu.
  4. In the Hypotheses drop-down list, select the null and alternative hypothesis.
  5. Optional: To compare the p-value against a predefined significance level, in the Significance level edit box, type the maximum probability of rejecting the null hypothesis when in fact it is true (typically 5% or 1%).
  6. Click Recalculate.
