J\u00e4rgnevalt anal\u00fc\u00fcsitakse v\u00f5rdlustestide tulemusi.

Lisaks arvutati efekti suurus, kasutades mitteparameetrilist statistikut Cliffi delta (Cliff \u03b4), sest testide tulemused ei olnud normaaljaotusega. Cliffi delta j\u00e4\u00e4b vahemikku \u22121\u2264\u03b4\u22641.

\u00dckskeelsete laste r\u00fchmade puhul oli k\u00f5igi testide eristusv\u00f5ime v\u00e4ga hea (p < 0,01; AUC \u22650,80, Cliff \u03b4 \u22650,65; vt tabel 5). Kakskeelsete laste puhul n\u00e4itas Mann-Whitney U-test olulisi erinevusi laster\u00fchmade vahel. Nii eesti- kui ka venekeelne LJT olid v\u00e4ga hea eristusv\u00f5imega (AUC \u22650,80; Cliff \u03b4 \u22650,64; vt tabel 6). S\u00f5navaratestide puhul oli efekti suurus keskmine (Cliff \u03b4 \u22650,34\u20120,37) ja eristusv\u00f5ime n\u00f5rk (AUC=0,67\u20120,68). See n\u00e4itab, et \u00fckskeelseid lapsi eristavad k\u00f5ik testid suurep\u00e4raselt, kakskeelsete puhul s\u00f5navaratestide alusel keelepuudega lapsi eakaaslastest eristada ei saa.<\/p>\n\n\n\n
