q2 · i? · design · r2

Single-group pre-post evaluation of the online PD with 50 K-12 personnel; the Wilcoxon signed-rank test was used because data were not normally distributed. The article reports a statistically significant increase, with "a mean of 9.02 to the post-test with a mean of 10.48"; no effect size is printed.

"The Wilcoxon signed-rank test shows that the knowledge level of all participants increased significantly after taking this PD (V = 265.50, P = 0.012 < 0.05) from the pre-test with a mean of 9.02 to the post-test with a mean of 10.48."

Discussion¶

Related Claims¶

• Knowledge gains from the cybersecurity PD differed by technology background: participants without a technology background improved significantly while those with one did not — a narrower finding that bears on this claim
• Knowledge gains were concentrated in module 2 and the awareness dimension: ask and action knowledge remained unchanged after the PD — a narrower finding that bears on this claim
