BSNC 5060 FINAL questions with
complete solutions passed
control - correct answer ✔✔The measures used to hold uniform or constant
the conditions in a research study
confidence interval - correct 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.
alpha - correct 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
clinical question - correct 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.
alpha coefficient - correct 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
accessible population - correct answer ✔✔A population that meets the population criteria and is
available
bias - correct answer ✔✔A distortion in the interpretation of the results of
the data analysis.
Dependant variable - correct 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.
,cluster sampling - correct 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
alternate form reliability - correct 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.
findings - correct answer ✔✔The statistical results of a study and the conclusions, interpretations,
recommendations, generalizations, and implications for future research and nursing practice
Analysis of Covariance (ANCOVA) - correct 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.
objectivity - correct answer ✔✔The use of facts without distortion by
personal feelings or bias
Directional hypothesis - correct answer ✔✔A hypothesis that specifies the expected direction of the
relationship between independent and dependent variables
convenience sampling - correct answer ✔✔A non-probability sampling strategy in which the most
readily accessible persons or objects serve as participants or participants of a study.
Auditability - correct 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.
Generalizability - correct answer ✔✔The extent to which data can be inferred to be representative of
similar phenomena in a population beyond the studied sample
, Analysis of Variance (ANOVA) - correct 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.
limitations - correct answer ✔✔The weaknesses of a study
Chi-square - correct answer ✔✔A nonparametric statistic used to determine whether the frequency
found in each category is different from the frequency that would be expected by chance.
accuracy - correct answer ✔✔The characteristic of all aspects of a study
systematically and logically following from the
research problem.
chance error - correct answer ✔✔An error attributable to fluctuations in subject characteristics that
occur at a specific point in time and are often beyond the awareness and control of the examiner; an
error that is difficult to control,
unsystematic, and unpredictable and thus cannot be corrected. Also called random error
data saturation - correct answer ✔✔A point when the information collected by the researcher becomes
repetitive; ideas conveyed by the participant have been shared previously by other participants, and
inclusion of additional participants does not result in new ideas.
hypothesis - correct answer ✔✔A best guess or prediction about what a
researcher expects to find with regard to the
relationship between two or more variables.
pilot study - correct answer ✔✔A small, simple study conducted as a
prelude to a larger-scale study (which is often called
the "parent study").
independent variable - correct answer ✔✔The antecedent or variable that has the presumed effect on
the dependent variable. The independent variable is manipulated in experimental research studies
