4. Question 4

   8 Points

   Which of the following is not part of decision analysis

   2. probability

   3. expected life expectancy

5. Question 5

   8 Points

   A patient was told by her doctor to that she had a choice of taking a medication or not taking the medication. Are those two options mutually exclusive of each other.

   1. Yes

   2. No

   3. Depends on the illness or circumstances of the illness.

6. Question 6

   8 Points

   The final value that is obtained on the decision analysis tree is known as the __________.

   1. expected probability

   2. the choice to evaluate

   3. the independent variable

   4. the dependent variable

7. Question 7

   8 Points

   In chapter 6 the author refers to a “cohort”. What does he/she mean by cohort?

   1. the method of calculating life expectancy for a age group

   2. a type of study

   3. a group of people that share at least one characteristic.

8. Question 8

   8 Points

   Life expectancy at birth tends to _______ from year to the next.

   1. Stay the same, because life expectancy can not change.

   2. Increase, because of health interventions

   3. Decrease, because as people get older they have less years to live

   4. None of the above.

9. Question 9

   8 Points

   Life expectancy refers to

   1. the average number of years remaining for an individual or a group of people at a given age

   2. the absolute age that a person is expected to die

   3. the average number of years remaining for and individual or group of people within a country regardless of age.

10. Question 10

    10 Points

    Sensitivity analysis allows to test or evaluate how the health outcome changes over a range of uncertain inputs to include

    1. structural uncertainty.. to allow for changes in the decision arm of the model, other things remaining the same

    2. parameter uncertainty .. allows for changes in the probability, other things remaining the same

    3. A and B

    4. none of the above

11. Question 11

    8 Points

    Sensitivity analysis

    1. is stress test of the decision model about how the health outcome will change with changes in costs and probabilities

    2. refers to changes probabilities as parametric

    3. refers to changes in decision arm as structural uncertainty

    4. all of the above

12. Question 12

    10 Points

    One way sensitivity analysis

    1. uses a single variable to test a range of values on the expected value of a strategy, other variables held constant

    2. uses two variables simultaneously to tests a range of values on the expected value of a strategy, other variables held constant

    3. refers to a Tornado diagram, where each variable is sequentially tested in a one way sensitivity analysis

    4. none of the above

Answer 1

Answer 1: True.

Decision analysis is a kind of approach that could be performed when there is uncertainty in the conditions. It includes that any uncertain events could arise. It allows to evaluate the values and preparedness.

Answer2: False

Decision analysis model provides the guidance for the uncertain events that could arise.
