BSNC 5060 FINAL Latest Update 2024-2025 Exam 150 Questions and 100% Verified Correct Answers Guaranteed A+
accessible population - CORRECT ANSWER: A population that meets the population
criteria and is available
accuracy - CORRECT ANSWER: The characteristic of all aspects of a study
systematically and logically following from the research problem.
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
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
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.
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.
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.
attrition - CORRECT ANSWER: The loss of a subject from a study between
time 1 data collection and time 2 data collection. Also called mortality.
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.
bias - CORRECT ANSWER: A distortion in the interpretation of the results of
the data analysis. 1 / 2
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
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.
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.
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
cohen's kappa - CORRECT ANSWER: The level of agreement observed beyond the
level that would be expected by chance alone.
concurrent validity - CORRECT ANSWER: The degree of correlation between two
measures of the same concept that are administered at the same time
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.
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.
constant error - CORRECT ANSWER: An error attributable to the lasting characteristics of the subject that do not tend to fluctuate from one time to another.
construct validity - CORRECT ANSWER: The extent to which a test measures a
theoretical construct or trait
content validity - CORRECT ANSWER: The degree to which the content of the measure represents the universe of content or the domain of a given behaviour
contrasted-groups approach - CORRECT ANSWER: A method used to assess
construct validity. A researcher identifies two groups of individuals who are suspected of having either an extremely high or an extremely low score on a characteristic; scores
