Exploring the fundamentals of research design in psychology, this overview covers experimental, correlational, and observational studies. It delves into quantitative and qualitative research paradigms, the use of interviews, questionnaires, case studies, and observational methods. The text emphasizes the importance of a robust design for validity and reliability in psychological research, highlighting various experimental designs and the significance of data collection techniques.

Research design provides a structured approach for collecting, analyzing, and interpreting data in psychology studies
Research design is shaped by the hypothesis, participant characteristics, and research environment to address specific research questions
A robust research design is pivotal for ensuring the validity and reliability of study outcomes in psychology research
Research design determines the type of study, whether it is experimental, correlational, or observational
The type of research design also dictates the appropriate methodology, whether it is quantitative, qualitative, or a mix of both
Psychological research encompasses two primary paradigms: quantitative and qualitative
Experimental research involves manipulating an independent variable to observe its effect on a dependent variable
The three primary experimental designs are between-subjects, within-subjects, and matched-pairs designs
Experimental research can be conducted in laboratory, field, or natural settings, each with varying levels of control and ecological validity
Qualitative research focuses on obtaining detailed and descriptive data through methods such as interviews, focus groups, and content analysis
Qualitative research is well-suited for exploring complex phenomena and understanding participant experiences
Qualitative research can also be used to generate hypotheses for further investigation

Types of research design in psychology
Experimental, correlational, observational—each determines the study's structure and methodology.
01
Methodology categories in research design
Quantitative (numerical data), qualitative (descriptive data), mixed methods (combination of both).
02
Importance of participant characteristics
Influences research design to ensure the study is relevant and results are generalizable to the population.
