1 Analysis of Covariance The function of Experimental design is to explain the effect of a IV or DV while controlling for the confounding effect of extraneous variables.

2 Analysis of Covariance When extraneous variable are not controlled the results of the measurement can not be attributed to solely the experiment treatment.

3 Analysis of Covariance ANOCOVA - combination of ANOVA and linear regression present a covariant as another variable that the groups may differ on.

4 Analysis of Covariance 1. Effect of two different teachings situations on clinical performances in clinical 2. Previous GPA may be a factor if not controlled 3. Control for GPA to find true effects of teaching strategies.
