Question
1. Comparing and contrasting single-sample and two-condition designs Aa Aa Which of the following experiments describes a single sample experiment? You want to compare the mean first-month weight gain of a random sample of premature babies to the known U.S. average first-month weight gain for all newborn babies. O You want to compare the mean number of years lived by chimpanzees that are raised in captivity and feda strict vegan diet to nonvegan chimpanzees that are also raised in captivity. So you compare the mean number of years lived by a sample of chimpanzees that are raised in captivity and fed a strict vegan diet to the mean number of years lived by the vegan chimpanzees' siblings, that are also raised in captivity but not fed a strict vegan diet. You want to compare the mean SAT scores of students before and after they complete a new SAT preparation course. So you compare the mean SAT scores of a randomly selected group of students before and after they completed a new SAT preparation course. You want to compare the mean SAT score of students who take a new SAT preparation course to that of students who don't take an SAT preparation course. So you compare the mean SAT score of a randomly selected group of students who took a new SAT preparation course to the mean SAT score of a randomly selected group of students who didn't take an SAT preparation course. single sample design? Which of the following describes an advantage of using a two-condition design over a dition design requires fewer subjects for the same degrees of freedom than a single sample design A two-con does. not require that the researcher specify the value of a population parameter for O A two-condition design does comparison prior to conducting the experiment.Explanation / Answer
Question Number 1 : THe option (a) Is correct.
Question NUmber 2 : A two condition design does not require that the researcher specify the value of population parameterfor comparison prior to conducting the experiment.
Queston Number 3 : THe two design which will use the same t or z test is
(a) Incependent groups and matched pairs
(b) Repeated measures and matched pairs
Quesetion Number 4 :
Experiment 1 : Independent Groups (Two independent groups involved )
Experiment 2 : Matched pairs (Same type of group)
Experiment 3: Repeatedd Measures (same conditions
