Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q1 i? Ambiguous preintervention functional forms are common in ITS applications, as are other factors affecting posttest means and slopes. → Manyee Wong 2015

Manyee Wong 2015¶
Manyee Wong, Thomas D. Cook, Peter M. Steiner. (2015). Adding Design Elements to Improve Time Series Designs: No Child Left Behind as an Example of Causal Pattern-Matching. Journal of Research on Educational Effectiveness, vol. 8, no. 2. https://www.mathematica.org/publications/adding-design-elements-to-improve-time-series-designs-no-child-left-behind-as-an-example-of-causal doi:10.1080/19345747.2013.878011
q1 · i? · theoretical · r?
The authors' methodological assertion, offered without accompanying data in the available text, that ambiguity in preintervention functional forms and other posttest-affecting factors are common threats to ITS designs.
"Ambiguous preintervention functional forms are common, as are other factors affecting posttest means and slopes."
