Question

The purpose of examining the validity of a research design includes all of the following except: a. Determining generalizability of findings b. Identifying threats to validity c. Judging the credibility of the researcher d. Determining if rival hypotheses or alternative explanations for finding might be possible.

Answer 1

The purpose of examining research design validity includes establishing the generalizability of findings, identifying potential threats to validity, and considering alternative explanations. However, judging the credibility of the researcher is not part of this process.

Step-by-step explanation:

The purpose of examining the validity of a research design involves several key objectives to ensure the integrity of a study. This includes determining the generalizability of findings, which relates to how well the results can be applied to contexts outside of the study. It is also important to identify threats to validity, which may include various biases or errors that can compromise the quality of the research. Another significant element is determining if rival hypotheses or alternative explanations for findings might be plausible, providing a comprehensive understanding of the studied phenomenon.

However, judging the credibility of the researcher is not the purpose of examining the research design's validity. While researcher credibility may affect the perception of the study, it is not an inherent aspect of the research design itself. Therefore, this option does not fall under the aim of assessing a study's validity.

Answer 2

The correct response is option D: Determining if rival hypotheses or alternative explanations for finding might be possible.

Step-by-step explanation:

A research design describes the research methods and techniques that the researcher used to collect their data. The research design should explain why the research methods are suitable for the subject matter. Examining the validity of a research design is done so that the credibility of the researcher can be established and so the readers and fellow scholars can assess for themselves if the study was carried out rigorously or whether there may be some limitations in the data. The researcher needs to list any known threats to validity and they should also explain to what extent the findings are generalizable.
