Analysis of Variance (ANOVA)

The basic principle of the inpatient prospective payment system (IPPS) is that the "levels" (no Complication or Comorbidity/Complication or Comorbidity/Major complication or comorbidity) of a MS-DRG family has different resource intensity and therefore should be paid differently.

Complete the following:

• Use the CHF data to test this hypothesis. Use charge as a measure of resource intensity. Be sure to state the null and alternative hypotheses, and set the alpha prior to performing the test.
• Conclude, if possible, which MS-DRGs have significantly different average charges.
