Guidelines for Critiquing Data Quality in Quantitative Studies

 

 

 

 

  1. Is there congruence between the research variables as conceptualized (i.e., as discussed in the introduction of the report) and as operationalized (i.e., as described in the method section)? (1 point)

 

 

 

 

 

 

  1. If operational definitions (or scoring procedures) are specified, do they clearly indicate the rules of measurement? Do the rules seem sensible? Were data collected in such a way that measurement errors were minimized? (1 point)

 

 

 

 

 

 

  1. Does the report offer evidence of the reliability of measures? Does the evidence come from the research sample itself, or is it based on other studies? If the latter, is it reasonable to conclude that data quality would be similar for the research sample as for the reliability sample (e.g., are sample characteristics similar)? (1 point)

 

 

 

 

 

 

  1. If reliability is reported, which estimation method was used? Was this method appropriate? Should an alternative or additional method of reliability appraisal have been used? Is the reliability sufficiently high? (1 point)

 

 

 

 

 

 

 

  1. Does the report offer evidence of the validity of the measures? Does the evidence come from the research sample itself, or is it based on other studies? If the latter, is it reasonable to believe that data quality would be similar for the research sample as for the validity sample (e.g., are the sample characteristics similar)? (1 point)

 

 

 

 

 

 

  1. If validity information is reported, which validity approach was used? Was this method appropriate? Does the validity of the instrument appear to be adequate? (1 point)

 

 

 

 

 

 

  1. If there is no reliability or validity information, what conclusion can you reach about the quality of the data in the study? (1 point)

 

 

 

 

 

 

  1. If a diagnostic or screening tool was used, is information provided about its sensitivity and specificity, and were these qualities adequate? (1 point)

 

 

 

 

 

 

  1. Were the research hypotheses supported? If not, might data quality play a role in the failure to confirm the hypotheses? (1 point)

 

 

 

 

  1. Do you need further instruction regarding quantitative data analysis to complete your research proposal? If so, what could the instructor provide to increase your understanding? (1 point)
