What is the difference between eta-squared for the correlated groups t test and eta-squared for the independent groups t test?

If a researcher used a matched-subjects design,which of the following statistical tests should be used?

If the sample size is less than 15,the correlated groups t test may show inflated Type I errors for data that are:

Why is the correlated groups t test usually more powerful than the independent groups t test?

The major difference between the correlated groups t test and the independent groups t test is that the former is used when the independent variable is manipulated and the latter is used when the independent variable is observed.

Dr.Hinson wants to investigate if rats fed a diet enriched with omega will do better at a maze learning task then when these same rats are given a normal diet.He has a total of 30 rats for his experiment.If Dr.Hinson fails to implement the appropriate changes to his experiment a potential confound may be_____.

If we were to compute the average nullified score across conditions for each individual in a correlated groups study,we would find that every individual would have _____ average score(s) .

The dependent variable must be ____________________in nature if a correlated groups t-test is used.

An important methodological problem to consider in a correlated-groups design is ______.

If the sample size is less than 15,the correlated groups t test may show inflated Type I errors for data that are markedly skewed.

If the effects of individual differences have not been removed from the raw scores,the eta² for the correlated-groups case would be _____ than if they have been removed,everything else being equal.

There is less variability in a set of nullified scores because the effects of individual differences in background have been removed.

The ____________________in a correlated groups t-test is similar to the sampling distribution of the difference between two independent means in a independent groups t-test.

Which of the following conditions would preclude the use of a correlated-groups design?

Although the correlated t test is usually a more powerful statistical test than the independent groups t test,one exception to this is

The correlated groups t-test is only used when the independent variable is____________________.

The correlated groups t test is _____ to violations of the normality assumption.

The formula for computing eta-squared from t and its degrees of freedom for the correlated groups t test is the same as that for the independent groups t test.
