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.
q2 i? Post hoc Scheffe comparisons place demonstration first, inquiry second, discussion third and lecture last in student performance. → Vincent E. Onweh and Udeme Timothy Akpan 2014
q2 i? The difference between inquiry and discussion was not statistically significant (significance .623). → Vincent E. Onweh and Udeme Timothy Akpan 2014

q2 · i? · causal · r2
Scheffe post hoc analysis across the four strategy groups. Demonstration showed positive mean differences against lecture (7.4268), inquiry (3.1944) and discussion (4.1944), all significant at .000; the inquiry-versus-discussion mean difference of 1.0000 had a significance of .623, so that pair did not differ significantly.
"The Multiple (Scheffe) Comparison Analysis indicates that the performance of students in Electrical Installation is highly observed in demonstration group, followed by students taught with inquiry strategy, discussion strategy and the least performance is seen in lecture group."
