Guidelines for Critiquing Data Quality in Quantitative Studies   Total points 40

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)? (4

points)

2.    If operational definitions (or scoring procedures) are specified, do they clearly indicate the

rules of measurement? How was data collected?(4 points)

3.    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? (4 points)

4.    If reliability is reported, which estimation method was used? Was this method appropriate? Is

the reliability sufficiently high? (4 points)

5.    Does the report offer evidence of the validity of the measures and the data? (4 points)

6.    If validity information is reported, which validity approach was used? Was this method

appropriate? Does the validity of the instrument appear to be adequate?   (4 points)

7.    If there is no reliability or validity information, what conclusion can you reach about the

quality of the data in the study? (4 points)

8.    If a diagnostic or screening tool was used, is information provided about its sensitivity and

specificity, and were these qualities adequate?  (4 points)

9.    Were the research hypotheses supported? If not, might data quality play a role in the failure

to confirm the hypotheses? (4 points)

10.      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? (4 points)
