Question
neuroscientist is investigating language deficits associated with damage to a particular area of the brain. e researcher has recruited six patients with damage to the left anterior temporal lobe, and has also tested normal subjects who were matched to the brain-damaged patients on age, IQ, and gender. He administered a vocabulary test to both groups, and now wishes to test whether the means are equal. Name the statistical test that would be appropriate. Be precise. 6. You are planning to examine whether meditation helps reducing the stress associated with the PSYC1 Midterm 2. In your experiment, you have two groups: a control group in which students DO NOT meditate, and an intervention group in which students DO meditate. Students are randomly assigned to either the control or experimental group. You measure the level of stress for both groups. Name the statistical test that would be appropriate to test the effect of meditation on stress reduction. An exclusive club for smart people claims to have members with an average 1Q of 140. Y the accuracy of the claim. You sample 20 members at random and administer an IQ test should you use? ou wish to test test. Which statistical 7.Explanation / Answer
5 ) Here we have two independent samples . Here we are interested to test the equality of means . Thus , a two sample t-test of means will be appropriate for this study .
6 ) Here we have two independent samples . Here we are interested to test the equality of means . Thus , a two sample t-test of means will be appropriate for this study .
7 ) Here we have to conduct a test of mean . Thus a one sample t test of mean will be appropriate . However , if the value of the population standard deviation is provided , then one can also use a one sample z test of mean for this problem .
