. propose a between-subjects experimental design to test the relationship. The IV and DV are already identified for you. Please explain how you would investigate the relationship by including: (1) your hypothesis (.e., what do you expect to happen), (2) an operational definition for your dependent variable (i.e., how will you test the variable), (3) the population (who do you want to recruit and why), (4) the levels of the IV (how many, what they are, and why), and (5)...

For each example, identify the test or interval to be used. Then state and check (as far as possible) the conditions. 1. A researcher takes 200 males over the age of 50 and randomly divides them into 2 groups. Group A takes one aspirin tablet per day, and group B takes a placebo tablet each day. After one year, the researcher records whether or not each subject has had a cardiovascular event (heart attacks, strokes, etc). She wishes to test...

Subject bias can occur in an experiment when the participants are aware of the purpose of the study and respond in a way that they think the researchers want. For example, if participants believe they are in a study to test if coffee improves your mood, those who drank coffee might claim to be happier than they really are. Based on the information given, which of the following experiments is most likely to have the issue of a control or...

Il. You test your diabetes drug (to control blood glucose levels) in laboratory rats which are genetically engineered to have diabetes. You give the drug to six (6) of your diabetic rats, and give another six (6) diabetic rats a placebo (which does not contain the drug), and compare blood glucose levels in the two groups of rats. The measurements of blood glucose levels for both groups of rats, along with means and standard deviations for each group, are given...

2. Identifying related samples Aa Aa E For each of the following research scenarios, decide whether the design uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures. (Note: Researchers can match subjects by matching particular characteristics, or, in some cases, matched subjects are naturally paired, such as siblings or married couples.) Lorrin Koran has studied whether antidepressants are effective for treating kleptomania. Suppose that people with kleptomania typically score...
