QUESTION 1 Discuss empirical research and its components
and provide examples where necessary. (15 marks)
Empirical Research: Overview and Components
Empirical research refers to the systematic investigation of observable phenomena through the
collection and analysis of data. It relies on empirical evidence derived from experience,
experiments, or observations rather than solely on theoretical considerations. Empirical research
is fundamental in various fields such as psychology, sociology, education, and natural sciences,
as it helps validate or refute theories based on real-world data.
Components of Empirical Research
1. Research Question or Hypothesis:
o This is the foundation of the research, stating what the researcher aims to
investigate. A well-formulated hypothesis is a specific, testable prediction about
the relationship between two or more variables.
o Example: "Does regular physical exercise improve mental health among
adolescents?"
2. Literature Review:
o A review of existing research related to the topic helps contextualize the study. It
identifies gaps in the current knowledge base, informs the research design, and
provides a theoretical framework.
o Example: Reviewing studies that have explored the impact of physical activity on
mental health, highlighting inconsistencies or unanswered questions.
3. Research Design:
o This refers to the overall strategy used to integrate the different components of the
study in a coherent and logical way. It includes selecting a methodology
(qualitative, quantitative, or mixed methods), and determining how data will be
collected and analyzed.
o Example: A quantitative approach using a controlled experimental design where
one group engages in regular exercise while a control group does not.
4. Data Collection:
o This involves gathering information through various means, such as surveys,
interviews, experiments, or observational methods. The choice of data collection
method depends on the research question and design.
o Example: Administering a questionnaire measuring mental health symptoms
before and after a 12-week exercise program.
