Aa Aa Although it is known that a particular therapy is effective for reducing depression, a researcher would like to determine how much effect the therapy has. A sample of depressed patients is obtained, and each individual is give a depression test. After four weeks of therapy, their depression is measured again. The scores from the depression tests are used to estimate the mean difference in depression. Which estimation equation should the researcher use? cannot be determined from the information given O The single-sample t equation O The independent-measures t equation O The repeated-measures t equationExplanation / Answer
option(d) the repeated measure t equations as the data is dependent
A repeated-measures study is one in which a single sample of subjects is used to compare two (or more) different treatment conditions. Each individual is measured in one treatment, and then the same individual is measured again in the second treatment. Thus, a repeated-measures study produces two (or more) samples of scores, but each sample of scores is obtained from the same sample of subjects
