DESIGNS CERTIFICATION SCRIPT 2026
QUESTIONS WITH SOLUTIONS GRADED A+
◍ Hypotheses.
Answer: Four categories: 1) associative versus causal.2) simple versus
complex.3) nondirectional versus directional.4) null versus research.
◍ Type I Error.
Answer: When the null hypothesis (opposite of hypothesis) is true. 5% or
lower probability of rejecting the null hypothesis in research.
◍ Research question.
Answer: a concise, interrogative statement that is worded in the present
tense and includes one or more of the study's principal concepts. Is usually a
rewording of the study's purpose.
◍ Dependent variable.
Answer: the result or outcome that is the study's focus.
◍ theory.
Answer: a scientific representation of reality that includes concepts and
relationships among concepts. consists of a set of concepts that are defined
and interrelated to present a unified view of a selected phenomenon
◍ Steps in quantitative research process.
Answer: 1) Choice of problem area and purpose.2) Review of the literature,
identification of research gap.3) Formulation of a research question,
objective, or hypothesis.4) Selection of research design.5) Identification of a
framework for the study if appropriate.6) Definition of study variables, both
conceptually and operationally. 7) Definition of population and sample.8)
Choice of methods of measurement and data analysis. 9) Formulation of a
, plan for data collection.10) Definition of how an intervention will be
enacted. .11) Implementation of a pilot study if one is to be employed.12)
Revision based on the pilot study, if indicated. 13) Implementation of the
study itself.14) Analysis of data.15) Interpretation of outcomes.16)
Communication of findings.
◍ dialectical reasoning.
Answer: involves looking at situations in a holistic way. believes that the
whole is greater than the sum of the parts and that the whole organizes the
parts.
◍ Operational definition.
Answer: makes a concept measurable, indicting the way it will be measured
in a particular study.
◍ Two main types of quantitative research.
Answer: interventional-includes experimental and quasi-experimental
designs and noninterventional-include descriptive and correlational designs.
◍ Design validity.
Answer: construct validity, internal validity, external validity and statistical
conclusion validity.
◍ Replication.
Answer: essential for the development of evidence-based knowledge for
practice and consists of four types: exact, approximate, concurrent, and
systematic.
◍ Type II Error.
Answer: The probability (set at 20%) of accepting the null hypothesis when
it is false. xz
◍ personal experience.
Answer: defined as the knowledge that comes from being personally
involved in an event, situation, or circumstance.
◍ Conceptual definition.
