Solution Manual for Statistics for
Nursing Research Questions And
Answers 2026
Ultimate Goal of Research - to develop, refine, and expand a body of knowledge
Aim of EBP - to reduce wide variations in individual clinician's practices, enhance best practice,
and reduce costs and improve quality
Evidence Based Practice (EBP) - A problem solving approach to clinical practice that integrates:
1.A systematic search for the most relevant evidence to answer a clinical question
2. One's own clinical expertise
3. Patient preferences and values
Best Nursing Practices - practices that are based on the best evidence available from nursing
research
Goal of best nursing practices - to apply the most recent, relevant and helpful interventions,
based on research, in real life practice
Quantitative research is - the building blocks of theories
Continuous variable - a variable that can take all the possible values within a range
Discrete variable - a variable that can only be a whole number on a range of set values (can't be
decimals or fractions)
, Categorical variable - assigning numbers as labels to data
Confounding (extraneous) variable - factors that interfere with the relationship between the
independent and dependent variables
Independent variable - The presumed cause; stimulus or activity that is manipulated or varied
by research; the element changed by the researcher
Dependent variable - the presumed effect; response, behavior, or outcome that the researchers
wants to predict or explain; caused by the independent variable
conceptual definition - the abstract or theoretical meaning of the concepts being studied
Operational definition - the procedures required to measure concepts; definitions that explicitly
state how a variable is measured
Problem Statement - well-structured formulation of what it is that is problematic
Purpose Statement - summary of the overall goal or aim of the study
simple hypotheses - relationship between 2 variables
complex hypotheses - relationship among three or more variables
directional hypotheses - tells the expected direction of a relationship
non-directional hypotheses - no indication of the relationship
