The Scientific Research Proposal
What you must understand
A proposal is an argument that a question is worth asking and can be answered. It needs a research question that is focused, answerable and ethically permissible, ideally expressed with an independent variable, a dependent variable and a specified population. The hypothesis should be directional or clearly stated and must be falsifiable. A literature review establishes the gap: what is known, what is contested, and what your study adds. The methodology must specify sampling, sample size justification, controls, standardised procedures and the statistical or analytical approach. Ethics covers informed consent, confidentiality, minimisation of harm, and animal or human ethics approval. A risk assessment identifies hazards and mitigation. Feasibility - time, equipment, cost, access - is assessed alongside significance and innovation.
Traps in questions
A common trap is a proposal whose question is too broad ('Does music affect learning?') - it lacks variables and population. Another is operationalisation failure: 'stress' or 'engagement' is named but never defined by a measurable indicator. Watch for missing controls, unjustified sample sizes, and sampling bias such as volunteers or convenience samples presented as representative. Questions often reward spotting that a proposal promises causation from a correlational design. Also distinguish aim (broad purpose), objective (specific step) and hypothesis (testable prediction).
Worked example
Weak: 'Investigate whether sleep affects exam performance.' Strong: 'Compare mean test scores on a standardised 30-item quiz between Year 11 students who report 6 hours or less of sleep and those reporting more than 8 hours on the night before, controlling for prior quiz score.' The second names variables, population, measure and a control.
