Construct Validity in Software Engineering Research and Software Metrics

Ralph, Paul, Tempero, Ewan·2018·Proceedings of the 22nd International Conference on Evaluation and Assessment in Software Engineering 2018

Abstract

Construct validity is essentially the degree to which our scales, metrics and instruments actually measure the properties they are supposed to measure. Although construct validity is widely considered an important quality criterion for most empirical research, many software engineering studies simply assume that proposed measures are valid and make no attempt to assess construct validity. Researchers may ignore construct validity because evaluating it is intrinsically difficult, or due to lack of specific guidance for addressing it. In any case, some research inevitably produces erroneous conclusions, because due to invalid measures. This article therefore attempts to address these problems by explaining the theoretical basis of construct validity, presenting a framework for understanding it, and developing specific guidelines for assessing it. The paper draws on a detailed example involving 15 software metrics, which ostensibly measure the size, coupling and cohesion of Java classes.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Traditional metrics such as lines of code, number of tasks, or bugs fixed have been criticized for lacking validity and context.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
