What research design has the goal of determining a cause and effect relationship?
Experimental research, often called true experimentation
, uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study. The true experiment is often thought of as a laboratory study, but this is not always the case; a laboratory setting has nothing to do with it.
Which kind of nursing research study would be used to create or generate a new theory about a phenomenon?
Qualitative research
approaches a phenomenon, such as a clinical problem, from a place of unknowing and attempts to understand its many facets. This makes qualitative research particularly useful when little is known about a phenomenon because the research helps identify key concepts and constructs.
What does significance at the .05 level mean nursing research?
In nursing research, the most common significance levels are 0.05 or 0.01, which indicate a
5% or 1% chance, respectively of rejecting the null hypothesis when it is true
. A smaller p-value of . 01 as compared to a p-value of . 05 will decrease the chances of rejecting the null hypothesis when it is true.
Which of the following is the main goal of evidence based practice?
The goal of conducting EBP is
to utilize current knowledge and connect it with patient preferences and clinical
expertise to standardize and improve care processes and, ultimately, patient outcomes.
Which human needs was not included in Henderson’s 14 basic needs of patients?
d. Henderson did not include
sexuality
in the 14 basic human needs. … She proposed that these needs shaped the fundamental elements of nursing care. One of these needs is to keep the body clean, and the nurse is assisting the patient to meet this need because the patient is unable to perform the function for himself.
Which type of research is best for establishing cause and effect?
A controlled experiment
is the only research method that can establish a cause and effect relationship.
What are the examples of cause and effect relationship?
Cause and effect is the
relationship between two things when one thing makes something else happen
. For example, if we eat too much food and do not exercise, we gain weight. Eating food without exercising is the “cause;” weight gain is the “effect.” There may be multiple causes and multiple effects.
What is most useful in establishing cause and effect relationships?
Which of the following is most useful in establishing cause-and-effect relationships? Explanation: …
Surveys
suggest relationships, which experiments can help to show to be cause and effect.
What makes up evidence-based practice?
Evidence-based practice includes
the integration of best available evidence, clinical expertise, and patient values and circumstances related to patient and client management, practice management, and health policy decision-making
. All three elements are equally important.
Which level of evidence is best?
The systematic review or meta-analysis of randomized controlled trials (RCTs)
and evidence-based practice guidelines are considered to be the strongest level of evidence on which to guide practice decisions.
What are the different types of Grounded Theory?
Grounded theory has several distinct methodological genres:
traditional GT associated with Glaser; evolved GT associated with Strauss, Corbin and Clarke
; and constructivist GT associated with Charmaz. Each variant is an extension and development of the original GT by Glaser and Strauss.
What does p-value .0001 mean?
A fixed-level P value of . 0001 would mean that
the difference between the groups was attributed to chance only 1 time out of 10,000
.
What does p-value of 0.001 mean?
For example, if the P value is 0.001, it indicates that
if the null hypothesis were indeed true
, then there would be only a 1 in 1000 chance of observing data this extreme.
What is a 5% significance level?
The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates
a 5% risk of concluding that a difference exists when there is no actual difference
.
