Home>Homework Answsers>Nursing homework helpnursingNURSEHypothesis and VariablesScenarios:A researcher wonders how well the sense of smell functions during sleep. In general, we know that our sensory systems operate at a higher threshold during sleep. That is, a more intense stimulus is required to elicit a response during sleep than during wakefulness. Furthermore, we are less responsive during some stages of sleep than during others. Experiments using sounds suggest that we are less responsive during stages 3 and 4 sleep (deep sleep) than during stages 1, 2, or REM sleep (lighter sleep). Thus, the 4 – 16 researcher predicts that research participants will be less responsive to odors during stages 3 and 4 sleep than during the other stages of sleep. The researcher devises a system for delivering odors while college students sleep in the laboratory. Peppermint fragrance is delivered at specific times through a modified oxygen mask that the students wear while they sleep. Electrodes are attached to each student’s scalp, face, and chin to determine sleep staging. Electrodes are also attached to each student’s chest to record heart rate. A change in heart rate following presentation of the odor is used to indicate that the participant detected the odor.Instructions:Read the scenario above and answer the following questions:What is the research hypothesis?What is the independent variable?Is the independent variable a qualitative variable or a quantitative variable?  Explain.Why might the researchers want to use multiple dependent variables?Describe one limitation of this study.4 years ago19.10.20213Report issueAnswer(1)Miss Professor4.7(42k+)4.7(3k+)ChatPurchase the answer to view itNOT RATEDHypothesisandVariables.docx4 years agoplagiarism checkPurchase $4Bids(73)Jahky BEmily ClarePROF_ALISTERTopanswersFiona DavaColeen AndersonBrilliant GeekDiscount AnsAshley EllieProf Bila ShakaAmanda SmithDr. BeneveGuru OliviaTop Malaikabrilliant answersProf Nato(PhD)Michelle GeekProf. TOPGRADEDr Michelle MayaPapersGuruother Questions(10)Computer classHGPLaw discussion paper 5 pages minimPHI 103 Week 5 QuizPhysics II – PhotonsResearch and identify one emerging country and discuss why Marxism might be an attractive option for that country and its leaders.
