QUESTION
control
Answer:
The measures used to hold uniform or constant the conditions in a research study
QUESTION
confidence interval
Answer:
An estimated range of values, which are likely to include an unknown population parameter
calculated from a given set of sample data. Abbreviated CI.
QUESTION
alpha
Answer:
Considered an a priori probability because it is set before the data are collected. Also considered a
conditional probability because the null hypothesis is assumed to be true
QUESTION
clinical question
Answer:
A presentation of an idea that forms the foundation for a study; it is developed from the research
problem and results in the research hypothesis.
QUESTION
alpha coefficient
Answer:
A number between 0 and 1 that expresses the relationship between the error variance, true
variance, and the observed score. A correlation of 0 indicates no relationship; the closer to 1 the
coefficient is, the more reliable is the tool
QUESTION
accessible population
Answer:
A population that meets the population criteria and is available
,QUESTION
bias
Answer:
A distortion in the interpretation of the results of the data analysis.
QUESTION
Dependant variable
Answer:
In experimental studies, the presumed effect of the independent or experimental variable on the
outcome. Variation in the independent variable changes this effect. The dependent variable is
observed but not manipulated.
QUESTION
cluster sampling
Answer:
A probability sampling strategy that involves successive random sampling of units. The units
sampled progress from large to small. Also known as multistage sampling
QUESTION
alternate form reliability
Answer:
A reliability measure in which two or more alternate forms of a measure are administered to the
same participants at different times. The scores of the two tests determine the degree of
relationship between the measures. Also called parallel-form reliability.
QUESTION
findings
Answer:
The statistical results of a study and the conclusions, interpretations, recommendations,
generalizations, and implications for future research and nursing practice
QUESTION
Analysis of Covariance (ANCOVA)
Answer:
A statistic that measures differences among group means and uses a statistical technique to equate
the groups under study in relation to an important variable.
, QUESTION
objectivity
Answer:
The use of facts without distortion by personal feelings or bias
QUESTION
Directional hypothesis
Answer:
A hypothesis that specifies the expected direction of the relationship between independent and
dependent variables
QUESTION
convenience sampling
Answer:
A non-probability sampling strategy in which the most readily accessible persons or objects serve
as participants or participants of a study.
QUESTION
Auditability
Answer:
The characteristic of a qualitative study, developed by the investigator's research process, that
allows another researcher or a reader to follow the thinking or conclusions of the investigator.
QUESTION
Generalizability
Answer:
The extent to which data can be inferred to be representative of similar phenomena in a
population beyond the studied sample
QUESTION
Analysis of Variance (ANOVA)
Answer:
A statistic that tests whether group means differ from each other; instead of testing each pair of
means separately, ANOVA considers the variation among all groups.
