Expert Solution

Criteria you can use to evaluate the quality of research is as follows -

Research question
The research must be clear in informing the reader of its aims. Terms should be clearly defined, even more so if they’re new or used in specific non-spread ways. You as a reader should pay particular attention should to errors in logic, especially those regarding causation, relationship or association.

Sample
To provide trustworthy conclusions, a sample needs to be representative and adequate. Representativeness depends on the method of selection as well as the assignment. For example, random assignment has its advantages in front of systematic assignment in establishing group equivalence. The sample can be biased when researchers used volunteers or selective attrition. The adequate sample size can be determined by employing power analysis.

Control of confounding variables
Extraneous variation can influence research findings, therefore methods to control relevant confounding variables should be applied.

Research designs
The research design should be suitable to answer the research question. Readers should distinguish true experimental designs with random assignment from pre-experimental research designs.

Criteria and criteria measures
The criteria measures must demonstrate reliability and validity for both, the independent and dependent variable.

Data analysis
Appropriate statistical tests should be applied for the type of data obtained, and assumptions for their use met. Post hoc tests should be applied when multiple comparisons are performed. Tables and figures should be clearly labelled. Ideally, effect sizes should be there

Discussion and conclusions
Does the study allow generalization? Also, limitations of the study should be mentioned. The discussion and conclusions should be consistent with the study’s results. It’s a common mistake to emphasizing the results that are in accordance with the researcher’s expectations while not focusing on the ones that are not. Do the authors of the article you hold in hand do the same?

Ethics
Last but not least, ere the ethical standards met? For more information, refer to the APA’s Ethical Principles of Psychologists and Code of Conduct

Next, explain how these criteria are tied to epistemological and ontological assumptions underlying philosophical orientations and the standards of your discipline. Then, identify a potential ethical issue in qualitative research and explain how it might influence design decisions. Finally, explain what it means for a research topic to be amenable to scientific study using a qualitative approach.
