- A cardinal feature of the Scientific Method is that: a. theories must be supported by experimental evidence b. the causes of any observations should be derived from first principles c. relationships should be expressed using mathematical formulae d. explanations of phenomena must seem clear and logicalarrow_forwardDefine theory. an assumption or concession made for the sake of argument an idea used to account for a situation or justify a course of action. a generally accepted explanation for a set of data or observations; its validity has been tested by the scientific method. a conceptual model or explanation for a set of data, measurements, or observations.arrow_forwardIn the process of using the scientific method, a researcher: O Directly tests both the null and alternative hypotheses. O Directly tests only the alternative hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because the null hypothesis leads to a specific prediction that can be compared with data. O Can not directly test either hypothesis.arrow_forward

A research instrument can be employed to produce both objective measures and subjective narratives.ii. When there are discrepancies between the quantitative and qualitative sets of findings, it means there is no feasible explanation for the social phenomenon under investigation.iii. Qualitative data can be used to inform the formulation of hypotheses that can be tested via quantitative methods.iv. Mixed-methods research produces data of a higher level of quality and is therefore preferable to ‘single-method’ research whenever the budget allows.
