Homogeneity of Variance Assumption
Complete your Module 4 Assignment by the end of Week 4.
When using the test for homogeneity of variance, basically four outcomes or options can be considered if a violation of the homogeneity of variance
assumption is violated. These include:
Option 1:
Since a violation of the homogeneity of variance assumption occurred, the independent t-test may not be the appropriate statistical procedure for analysis of
data. Therefore, we may opt for a lower order non-parametric statistical test.
Option 2:
Since a violation of the homogeneity of variance assumption occurred, the independent t-test may not be the appropriate statistical procedure for analysis of
data. Therefore, we will abandon the test all together.
Option 3:
Even though we violated the homogeneity of variance assumption, we will continue to use the parametric measure due to the robust nature of the tests.
Option 4:
Resample with a larger sample size and retest.
Write a 3- to 4-page essay that discusses the pros and cons of each of the four options and which one you would most likely incorporate in your study.
Include your rationale for your choice and backed up with appropriate references and citations.
