QUESTION 1What are the degrees of freedom for a study that used a paired samples t-test and had 63 people in the study?QUESTION 2A study used a within the design and had a degree of freedom of df= 49. How many participants were in the sample? QUESTION 3Why do we not test for homogeneity with a paired samples t-test? we assume that the two samples we have chosen will have the same variance since the same sample is used in both conditions, we assume the data remains homogeneous the variance is too large that we cannot perform the test we assume there is no variability when using paired sample designs

QUESTION 1

What are the degrees of freedom for a study that used a paired samples t-test and had 63 people in the study?

QUESTION 2

A study used a within the design and had a degree of freedom of df= 49.
How many participants were in the sample?

QUESTION 3

Why do we not test for homogeneity with a paired samples t-test?

		we assume that the two samples we have chosen will have the same variance
		since the same sample is used in both conditions, we assume the data remains homogeneous
		the variance is too large that we cannot perform the test
		we assume there is no variability when using paired sample designs
