NURS 205 EXAM QUESTIONS WITH COMPLETE
SOLUTIONS!!/GRADE A+ GUARANTEED
SATISFACTION
Epidemiological studies - ANSWER-Examine factors affecting the health and illness of populations in
relation to their environment.
-investigates the distribution, determinants, and dynamics of health and disease.
-often prevalence or incidence focused.
Population descriptors - ANSWER-Inclusion: eligibility criteria
Exclusion: delimitations criteria
Sampling - ANSWER-Process of selecting a portion or subset of the designated population to represent
the entire population.
Representative sample - ANSWER-The key characteristics closely approximate those of the population.
Sampling strategies - ANSWER-Nonprobability: nonrandom.
Probability: randomization of sample, more likely to be representative of a population.
Nonprobability sampling - ANSWER-Convenience sampling
Quota sampling
Purposive sampling
Matching
Network or snowball effect sampling
Purposive Sampling - ANSWER--Effective pretesting of newly developed instruments with a purposive
sample of diverse types of people
-Validation of a scale or test with know-groups technique
-Collection of exploratory data in relation to an unusually or specific population
,-Collection of descriptive data that seeks to describe the lived experience of a phenomenon
-Focus of the study population relates to a specific diagnosis, condition, or demographic characteristic
Probability Sampling - ANSWER--Simple random
-Stratified random
-Multistage (cluster)
-Systematic
Conceptual definition - ANSWER-Derived from the literature, the accepted definition of a concept.
Operational definition - ANSWER-Translates the conceptual definition into behaviour or verbalizations
that can be measured.
Operationalizations - ANSWER-The process of translating a concept of interest to a researched into
observable and measurable phenomena.
Goodness of Fit - ANSWER-Between:
-purpose
-design
-research question or hypothesis
-conceptual and operational definitions
-data collection method
Data consistency - ANSWER-Achieved by measuring the data in the same manner for each subject.
Observational methods - ANSWER--Concealment without intervention
-Concealment with intervention
-No concealment without intervention
-No concealment with intervention
, Likert-Type Scale - ANSWER-Close-ended questions, scaled from a 1-5 rating.
Rigour - ANSWER-The quality, believability, and trustworthiness of the study finding.
-Research results should be transferable and generalizable.
Quantitative rigour - ANSWER-Psychometric measures used to ensure instrument reliability and validity.
Qualitative rigour - ANSWER-Shown by credibility, audibility, and fittingness.
Reliability - ANSWER-The extent to which the instrument yields the same results on repeated measures.
-stability
-consistency
-accuracy
-equivalence
Reliability coefficient - ANSWER-Expressed the relationship between the: error variance, true variance,
observed score.
-(RC) ranges from 0-1
0: no relationship
1: perfect relationship
.89: strong relationship
Validity - ANSWER-Refers to whether a measurement instrument accurately measures what it is
supposed to measure.
-precision
-accuracy
-consistency
