q2 · i? · associational · r2

Norming study across twelve schools in five cities: standard scores are smoothed values derived from the actual averages, which the author says differ very slightly from them. A per-school table and a standard curve (Figure 1) show attainment rising from about 10.3 in grade 1 to 83.7 in grade 8.

"The spelling tests have been made thus far, according to the specifications stated above, on 2500 pupils in twelve schools of five cities located in Wisconsin, Minnesota and New York."
