What are the three key processes that a research design should define?

• Data analysis, hypothesis testing, and data collection

• Data collection, instrument development, and data interpretation

• Data collection, instrument development, and sampling

• Hypothesis formulation, data collection, and statistical analysis

How do positivist research methods differ from interpretive methods in terms of their approach to research?

• Positivist methods use inductive reasoning, while interpretive methods use deductive reasoning.

• Positivist methods aim at theory testing, while interpretive methods aim at theory building.

• Positivist methods rely exclusively on qualitative data, while interpretive methods rely on quantitative data.

• Positivist methods focus on subjective interpretations, while interpretive methods focus on objective facts.

What are the four key design attributes that define the quality of research designs?

• Internal validity, external validity, construct validity, and statistical conclusion validity

• Hypothesis testing, data collection, sample size, and data analysis

• Data collection, data interpretation, research ethics, and sample representativeness

• Reliability, generalizability, measurement accuracy, and statistical significance

Define "internal validity" in the context of research design.

• The ability to generalize research findings to a broader population.

• The extent to which a measurement scale accurately represents the theoretical construct it is meant to measure.

• The degree to which observed changes in a dependent variable can be attributed to changes in the independent variable.

• The validity of statistical conclusions drawn from the research data.

What does "external validity" refer to in research design?

• The extent to which research findings can be applied to other research designs.

• The ability to control for extraneous variables in an experiment.

• The generalizability of research findings to populations or settings beyond the study.

• The reliability of the measurement instruments used in a study.
