Document Summary
May have to re-submit research project outline for more clarification. Project proposal: include 5 outside sources for the development of your rationale. Project proposals and ethics form due in 2 weeks. Advantages: restricts the discussion to that of which is observable, measurable, increases the repeatability of research and increases precision and consistency. Disadvantages: jargon not accessible to people outside the discipline, certain coldness to the operational definition. If variable is manipulated: eliminate confounds, determine the number of levels, determine strength of manipulation. It is not all abut if it is a correct operational definition, but rather if the operational definition is useful. How to know it is useful: apply some reasonable research and literature in the area and make reasonable connections. Common types: positive linear, negative linear, curvilinear, no relationship. Increases in one variable, leads to increases in another. Increases in one variable leads to decreases in another. Increases in one variable leads to increases then decreases in another.
