Repeated Measures ANOVA
... For the paired t test, which estimates the population correlation with the sample correlation coefficient, we have Var(difference) Var(Yi1 Yi 2 ) 12 22 2 1 2 so we get to substract off something to provide a smaller variance, which in turn produces a smaller standard error, which i ...

Estimating with Confidence
... Explain what is meant by margin of error. State in nontechnical language what is meant by a “level C confidence interval.” State the three conditions that need to be present in order to construct a valid confidence interval. List the four necessary steps in the creation of a confidence interval (see ...
