Final Project, Part 11:Evaluate Quantitative Study
· Do the researchers present an adequate rationale for conducting the study?
· What is the significance of the study? What difference will it make to the field?
· Is the literature review thorough and comprehensive?
· Do the researchers demonstrate any potential biases in the literature review?
· Are all important concepts clearly defined by the researchers?
· Do the researchers clearly describe previous methods that are relevant to understanding the purpose for conducting this study?
Evaluating the Purpose Statement and Hypotheses
· Does the article clearly state the purpose statement?
· Is the purpose statement clearly based on the argument developed in the literature review?
· Are the variables of interest (i.e., independent and dependent) clearly identified in the problem statement?
· What type of hypothesis is presented?
· Is there a clear rationale for the direction of the hypothesis, based on the literature review?
· Is the hypothesis testable and falsifiable?
· Is the hypothesis consistent with current theories or research?
· For populations that include 100 or fewer individuals, the entire population should be sampled.
· For populations that include 400–600 individuals, 50% of the population should be sampled.
· For populations that include 1,500 individuals, 20% of the population should be sampled.
· For populations that are 5,000 or larger, about 8% of the population should be sampled. (Note, however, that it is possible to have a sample that is so large that it does not justify the increased costs, and may produce significant differences that are too small to be meaningful).
· What type of research design was used?
· Was the research design consistent with the purpose and hypotheses?
· Did the researcher provide a detailed description of what was conducted?
· Did the researcher introduce any bias in the procedures used?
· Was the independent variable clearly defined?
· Were there any threats to the internal validity of the study?
· Were there any threats to the external validity of the study?
· Is there a clear and adequate description of the instrument (data collection measures) used?
· What types of instruments were used in the study (self-report inventories, ratings, etc.)?
· Are the instruments standardized?
· What are some of the potential problems or limitations with the types of instruments used?
· Does the instrument appear to be appropriate for the sample?
· Is the instrument consistent with the hypotheses?
· Is there a discussion about the reliability and validity of the instruments used?
· What descriptive statistics were used?
· Do the descriptive statistics adequately describe the sample?
· What types of inferential statistics were used?
· Are the inferential statistics used adequate to answer the hypotheses?
· Is the research design consistent with the statistical methods used?
· Did the researchers clearly restate the purpose and hypotheses?
· Did the researchers clearly discuss the implications of the findings and how they relate to theories, other findings, and actual practice?
· Did the researchers provide alternative explanations of the findings?
· Has there been appropriate generalization of significant findings beyond the sample to the population?
· Did the researchers identify potential limitations of the study and the results?
· Did the researchers identify possible directions for future research?
