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.

q3 · i3 · associational · r1

Pearson product-moment correlation analysis in 52 preschool children (mean age 69.19 ± 3.71 months) between Korean Alphabet Writing Assessment scores and BOT-2 fine motor precision. The study reports a "statistically significant correlation with fine motor precision (r=0.78)".

"handwriting legibility had a statistically significant correlation with fine motor precision (r=0.78) and a high correlation with manual dexterity (r=0.49)"

q3 · i3 · associational · r2

Same Pearson correlation analysis of 52 preschool children, for the BOT-2 manual dexterity sub-item against handwriting legibility, reporting "a high correlation with manual dexterity (r=0.49)".

"handwriting legibility had a statistically significant correlation with fine motor precision (r=0.78) and a high correlation with manual dexterity (r=0.49)"

q3 · i3 · associational · r2

Pearson correlation in the same 52-child sample between handwriting legibility and Functional Dexterity Test time (mean 32.98 ± 5.19 sec), showing "a statistically significant inverse correlation" with r=−0.68; faster in-hand manipulation related to better legibility.

"It also showed a statistically significant inverse correlation with the performance time of the Functional Dexterity Test (r=−0.68)"
