QUESTION 1

  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

    1. 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

      1. 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
