Subclaims¶

q2 i? Kruskal–Wallis tests showed significant differences among three map-visit-frequency groups on orientation ratio (H(2)= 10.0, P<0.05) and access ratio (H(2)= 11.8, P<0.05). → Stanton 1997 q2 i? Differences among the frequency groups on task-test scores were not statistically significant (H(2)= 5.8, P=0.06); students visiting the map 6–10 times scored highest, and heavy visitors (more than 11 times) were attributed high cognitive overhead. → Stanton 1997 (2)

q2 · i? · associational · r1

Causal-comparative Kruskal–Wallis analysis by ranks at the 0.05 level compared the three groups defined by map-visit frequency; only orientation and access ratios reached significance, with "H(2)= 11.8, P<0.05" for access. No effect size is printed.

"The results showed significant differences between the frequency of visit to the map relatively to the orientation ratio (H(2)= 10.0, P<0.05) and to the access ratio (H(2)= 11.8, P<0.05)."

q2 · i? · associational · r1

The same Kruskal–Wallis comparison found a marginal, non-significant difference on task-test scores (H(2)= 5.8, P=0.06); the 6–10-visit group "had the highest mean rank score".

"We also found a value of H(2)= 5.8 (P=0.06) for the variable task-test. Although not significant, the present value showed some differences among the three groups of frequency of visits to the map relatively to the score obtained in the task-test."
