?1- In an article entitled “The DeadGrandmother/Exam Syndrome and the Potential Downfall of AmericanSociety,” Biology professor Mike Adams provides evidence that “Astudent’s grandmother is far more likely to die suddenly justbefore the student takes an exam, than at any other time of theyear.” After the data, he reports “Only one conclusion can be drawnfrom these data. Family members literally worry themselves to deathover the outcome of their relatives’ performance on each exam.” Heelaborates that the worry causes high blood pressure, resulting infatal strokes and heart attacks.

For each question, choose the term that makes the statementtrue.

Prof. Adams has a predictive model in which exams causegrandmothers to worry, which in turn causes grandmother to die. Insuch a model, ___________________ is a mediating variable.

		taking an exam
		worry
		dying suddenly

??2- Situation: Under a new state law,hospitals must report the percentage of people undergoing backsurgery who exhibited “significant complications” aftersurgery.

Indicate whether the situation is appropriately described asmeasure management, and if it does, whether it is operationaldistortion or reporting distortion.

The hospital changes their policies to redefine severalpost-operative outcomes previously considered “significantcomplications” as being “non-significant complication”. Both thenew and old definitions are in compliance with State law.

		Reporting distortion
		Not measure management
		Operational distortion

3- In an article entitled “The Dead Grandmother/Exam Syndromeand the Potential Downfall of American Society,” Biology professorMike Adams provides evidence that “A student’s grandmother is farmore likely to die suddenly just before the student takes an exam,than at any other time of the year.” After the data, he reports“Only one conclusion can be drawn from these data. Family membersliterally worry themselves to death over the outcome of theirrelatives’ performance on each exam.” He elaborates that the worrycauses high blood pressure, resulting in fatal strokes and heartattacks.

For each question, choose the term that makes the statementtrue.

Prof. Adams measures grandmother death rates by counting thenumber of students who report that their grandmother has died.However, he needs to keep in mind that the number of reporteddeaths is just a ______________ that is capturing the______________ with a great deal of measurement error.

		moderating variable; proxy
		proxy; mediating variable
