Subclaims¶

q2 i3 Frequency and time of map visits correlated positively with orientation ratio (rho = 0.57 and 0.62) and access ratio (rho = 0.65 and 0.68). → Stanton 1997 q2 i? Despite the positive correlations, orientation and access were the ratios with the lowest values overall (0.13 and 0.16), so the map did not produce effective orientation or access. → Stanton 1997

q2 · i3 · associational · r1

Spearman correlation analysis in the same log-based study of 22 students. The printed effect sizes are rho = 0.57, rho = 0.62 (orientation) and rho = 0.65, rho = 0.68 (access); the largest, |r| = .68, is a large correlation. The authors note these ratios "have the lowest values (0.13 and 0.16, respectively)" in Table 2.

"in spite of a reasonable positive correlation between frequency/time of visit to the map and orientation ratio (0.57 and 0.62, respectively) as between frequency/time of visit to the map and access ratio (0.65 and 0.68, respectively)"
