Advantages of Discontinuous Panels and Causal Research

Research Design and Methods

• The main purpose of exploratory research is to explore and gain insights into a topic or issue.

Constructs and Hypotheses

• A construct is an abstract concept or idea that is used to understand a phenomenon or behavior.
• Hypotheses are educated guesses or predictions that are tested in research to support or reject a theory.
• Hypotheses are used to guide the research design and provide a framework for analysis.
• Hypotheses are considered tentative explanations or predictions that are tested in an investigation or argument.

Research Design

• Experiments involve manipulating independent variables to see their effect on dependent variables.
• Causal research involves determining causal relationships between variables.
• In an experiment, independent variables are manipulated to see their effect on dependent variables.
• Longitudinal studies differ from cross-sectional studies in that they involve observing participants over a longer period of time.
• Cross-sectional studies involve observing participants at a single point in time.
• Sample surveys are considered cross-sectional studies because they involve collecting data from a sample of participants at a single point in time.
• Descriptive research is undertaken to describe the characteristics of a population or phenomenon.
• The primary characteristic of cross-sectional studies is that they provide a snapshot of the population at a single point in time.

Experimental Design

• Before-after testing is a type of experimental design that involves testing hypotheses that specify relationships between variables.
• Pretest refers to the measurement of a variable before the intervention or treatment in an experiment.
• Posttest refers to the measurement of a variable after the intervention or treatment in an experiment.
• A/B testing involves comparing two versions of a product or service to determine which one performs better.
• Internal validity is concerned with whether the experiment is measuring what it claims to measure.
• External validity assesses whether the results of an experiment can be generalized to other populations or contexts.
• For an experiment to be considered valid, the researcher must be able to draw causal inferences about the relationship between the independent and dependent variables.

Focus Groups and Panels

• Focus groups are used in exploratory research to gain insights and understanding of a phenomenon.
• Discontinuous panels involve collecting data from the same participants at multiple points in time.
• The advantage of discontinuous panels is that they allow researchers to observe changes over time.
• Discontinuous panels are suitable for studying phenomena that change over time.

Units of Measurement and Causality

• The unit of measurement in research is the individual or case being studied.
• In causal research, causal relationships are often determined by manipulating independent variables and observing their effect on dependent variables.
