RESEARCH METHODS THINKING CRITICALLY WITH PSYCHOLOGICAL SCIENCE

THE SCIENTIFIC METHOD AND DESCRIPTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A research hypothesis with operationalised variables is
A
Whether the results are valid and reliable
B
The sample from which the populations was drawn
C
Whether the IV and DV can be controlled
D
How the IV and DV will be manipulated and measured
Explanation: 

Detailed explanation-1: -Operationalising means stating your IV and DV in ways that make it obvious how they are being manipulated or measured. In particular, an operationalised DV will create quantitative data. For example: Not “intelligence” but “score on a IQ test"

Detailed explanation-2: -An operational hypothesis in a research experiment clearly defines what the variables of interest are and how the different variables are related to each other. The operational hypothesis should also define the relationship that is being measured and state how the measurement is occurring.

Detailed explanation-3: -A hypothesis must include: The IV operationalised into different conditions. The DV operationalised to clearly show how behaviour is measured/ scored. The relationship expected (positive/ negative/ no).

Detailed explanation-4: -Abstract. Experimental research is a study that strictly adheres to a scientific research design. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared. Most importantly, experimental research is completed in a controlled environment.
