/ 3
pts
A sampling technique used in experimental design includes
Purposeful
Correct!
Randomization
Snowball
Voluntary selection
Question 3
3
/ 3
pts
A causal relationship is said to exist
Correct!
When the dependent variable changes as the independent variable is manipulated.
When the independent variable changes as the dependent variable is manipulated.
There is no change when either of the variables are manipulated.
Both variables change when the independent variable is manipulated.
Question 4
3
/ 3
pts
A researcher wants to know whether nursing fatigue is one cause of poor patient satisfaction scores. The independent variable is
Correct!
Nursing fatigue
Patient satisfaction scores
Both nursing fatigue and patient satisfaction scores
Number of hours worked by the nurse during the week previous to measuring patient satisfaction scores.
Question 5
3
/ 3
pts
Causality is tested through which of the following?
Grounded theory
Correct!
Experimental research
All quantitative research
Descriptive research
Question 6
3
/ 3
pts
The researcher must select an appropriate design for a study in order to eliminate error and make critique of the findings possible.
True
Correct!
False
Question 7
3
/ 3
pts
A mixed methods research design means two types of quantitative studies are used to collect and analyze the data.
True
Correct!
False
Question 8
0
/ 3

The purpose of ___________ in the health sciences is to create knowledge that will improve health, lengthen life, and decrease death and disability.
You Answered
Scientific method
Basic research
Correct Answer
Applied research
Correlational research
Question 9
3
/ 3
pts
Quantitative research can be described as
Correct!
objective and formal
subjective and formal
objective and informal
subjective and informal
Question 10
3
/ 3
pts
In quantitative experimental research, the independent variable is manipulated to determine the effects on the dependent variable.
Correct!
True
False
Question 11
3
/ 3
pts
The blueprint for quantitative studies is termed
Correct!
research design
research goal
research objective
research process
Question 12
3
/ 3
pts
Why does subject attrition affect internal validity?
A study in which the majority of the subjects die calls into question whether the treatment itself is safe
Correct!
Subjects who drop out may differ from those who stay in the study, in terms of an important extraneous variable.
Type I error is almost guaranteed with very unequal sample sizes.
Subject mortality may result in a sample that is so much smaller than anticipated that type II error may result.
