What does a beta value of a study do? - ANS.... -Describes the risk of
making a type 2 error (or false negative study results) *When reading that a
study has a high beta level, there could be a chance that the number of
complications between 2 groups is not comparable after all*
Ethnographic study is a sub-type of which type of research design? -
ANS.... -Qualitative
A type of non-random sampling in which participants are selected purely
based on convenience/availability? - ANS.... -Convenience sampling
What is the first step in data analysis of a survey with responses using
quantitative or categorical design? - ANS.... -Transform information into
numerical values called codes
Used to compare the mean performance of 2 independent groups? -
ANS.... -T test
Detects differences in 3 or more groups? - ANS.... -Analysis of variance
Used to compare distribution of a condition across 2 or more groups? -
ANS.... -Chi-squared
,After the problem and literature review are completed, what is the next
step? - ANS.... -Develop a hypothesis or a predictive statement about the
relationship between 2 or more variables
What is a theoretical framework? - ANS.... -When you specify a problem,
identify how a hypothesis will be developed and tested, and determine how
the findings will be interpreted and generalized for use.
Focuses on the feelings an perceptions of human experiences in a natural
setting? - ANS.... -Qualitative study
Focuses on the effects of identified variables when studied over a period of
time? - ANS.... -Longitudinal study
an average for a set of scores? - ANS.... -Mean
The middle value in a distrubution of scores or the value above and below
50% of the scores lie? - ANS.... -Median
Most frequently occurring value within a data set? - ANS.... -Mode
Where recommendations for changes in current practice based on the
research findings would be documented? - ANS.... -In the discussion
section
Where a description of the sample and procedures used during a study
would be documented? - ANS.... -In the methodology section

What type of subjects does a Phase 1 clinical trial study? - ANS.... -Healthy
human subjects
, What is an integral part of an experimental design? - ANS.... -Random
sampling
Where do you document data that has been categorized, labeled and
manipulated in a quantitative study? - ANS.... -In a codebook
Focuses on phenomenon of life experiences? - ANS.... -Descriptive study
A quantitative analysis that uses numeric results from multiple studies that
focuses on a single topic? - ANS.... -Meta-Analysis
Research summary of the findings and implications of the findings to
nursing practice? - ANS.... -Conclusion
An element of a true experimental design include? - ANS.... -An
explanation of how the dependent and independent variable will be
manipulated
When should an informed consent be obtained in a study? - ANS.... -After
seeking approval from the institutional review board
An action that is based upon results of a scientific study? - ANS.... -
Evidence-based practice
A true research hypothesis consists of? - ANS.... -Dependent and
independent variables and a study population
Describes how well results of a new tool compare to the results found on
established standards? - ANS.... -Criterion-related validity
