Question

. Comparing and contrasting single-sample and two-condition designs Which of the following experiments describes a two-condition experiment? O You want to test whether a sample of chimpanzees raised in captivity and fed a strict vegan diet for their lifetimes live longer than the known average life span for all chimpanzees living in captivity You want to compare the mean Hamilton depression scores of a random sample of teenage girls who attend a weeklong self-image camp to the known mean Hamilton score for teenage girls O You want to compare the mean SAT score of a randomly selected group of students who took a new SAT preparation course to the national average SAT score. O You want to compare the depression levels of teenage girls before and after attending a weeklong camp focused on improving self-image. So you compare the mean Hamilton depression scores of a randomly selected group of teenage girls before and after they attend a weeklong camp focused on improving self-image. Which of the following describes an advantage of using a two-condition design over a single sample design? A two-condition design assures that the conditions for the experimental group closely match those for the group that provides the comparison value(s). O When you use a two-condition design, the test statistic is easier to calculate. In a two-condition experiment, consider these three different designs: matched pairs, repeated measures, and independent groups. Suppose you want to compare means between the two conditions. Which two of these designs uses the same t test or z test? O Independent groups and matched pairs O Matched pairs and repeated measures in a two-condition experiment, consider these three different designs: matched pairs, repeated measures, and independent groups. Suppose you want to compare means between the two conditions. Which two of these designs uses the same t test or z test? O Independent groups and matched pairs O Matched pairs and repeated measures O Independent groups and repeated measures Identify the type of two-condition experiment for each of the following: Experiment Type of Two-Condition Experiment 1. You want to compare the mean number of years lived by chimpanzees that are raised in captivity and fed a 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. 2. You want to compare the depression levels of teenage girls before and after attending a weeklong camp focused on improving self-image. So you compare the mean Hamilton depression scores of a randomly selected group of teenage giris before and after they attend a weeklong camp focused on improving self-image 3.You Experiment Type of Two-Condition Experiment 1. You want to compare the mean number of years lived by chimpanzees that are raised in captivity and fed a 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. 2. You want to compare the depression levels of teenage girls before and after attending a weeklong camp focused on improving self-image So you compare the mean Hamilton depression scores of a randomly selected group of teenage girls before and after they attend a weeklong camp focused on improving self-image. 3. 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 randomiy 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.
