q2 i? Average scale grade increased with age from 6 to 14; drops at 14 and 16 are reported but post-15 standings are judged uninformative. → King 1912

Evidence¶

King 1912¶

King, I., & Johnson, H. (1912). The writing abilities of the elementary and grammar school pupils of a city school system measured by the Ayres scale. Journal of Educational Psychology, 3(9), 514–520. doi:10.1037/h0071006

q2 · i? · associational · r1

Age distribution of ranks for 817 pupils (some specimens were thrown out because no age was given), grades copied by pupils in their ordinary hand. Descriptive averages only; the article itself cautions that older-age cases are too few.

"The age progress is steady up to 14, when there is a slight drop, and another drop is shown by the four cases of 16 years. The standings, however, beyond 15 years are probably not indicative of anything, as the cases are then too few."
