A research question in experimental-type research has which of the following characteristics?
A It broadly reflects mulitple problem statements.
B It is posted a priori or before entering the field.
C It can be changed midstream in the study.
C It may be both descriptive and predictive.
The correct answer and explanation is:
The correct answer is B: It is posted a priori or before entering the field.
In experimental-type research, the research question is typically formulated before the study begins, known as a priori. This means the question is designed based on existing theories or literature, providing a clear focus for the study. This prior formulation helps in structuring the experiment, determining variables, and selecting appropriate methods. The clarity and specificity of the question guide the entire experimental process, from hypothesis testing to data analysis.
The reason the research question is posted before entering the field is because experimental studies often involve controlled environments where independent variables are manipulated to observe effects on dependent variables. These manipulations require a well-defined question to ensure that the results are relevant and the conclusions valid. The research question forms the basis for developing hypotheses, which can be tested through controlled experimentation.
While experimental research is often structured, it may allow slight modifications or adaptations in some cases. However, the core of the research question remains focused and defined from the outset to maintain consistency and validity in the study.
Choices A, C, and D are less characteristic of experimental-type research. Experimental research focuses on testing specific hypotheses derived from a clearly defined question. It does not broadly reflect multiple problem statements, nor is the question typically changed midstream. Though experimental research can lead to descriptive or predictive insights, its primary goal is to establish cause-and-effect relationships through manipulation of variables, making the question more predictive in nature rather than both descriptive and predictive.
