Resumo: The study presents the effect sizes, their confidence intervals, ratings, and visualizations for the 2018 normative update of the R-1 Nonverbal Intelligence Test, since the statistically calculated differences based on the p-value offer tenuous evidence against the null hypothesis and do not serve as a proof of clinical significance. We used the normative sample of the instrument, consisting of 5,595 adults of both sexes, aged 18 to 65 years, from the five Brazilian geographic regions and subdivided by elementary, middle, and high school levels. The results showed medium to large effect sizes in the comparison between elementary and high school levels; large to very large in the relation between elementary and high school; and small to medium effect sizes between high school and high school levels. It was concluded that the statistically observed differences, by means of variance and Tukey's post-hoc analyses reflect a real effect when considering the impact of the education level variable on test performance. It was understood that normative studies of the instrument reflect a real impact when considering the variable under study, and should include the effect size and their respective confidence intervals. Keywords: Intelligence test; standardization; effect size.

Utilizou-se a amostra normativa do instrumento, composta por 5.595 adultos, de ambos os sexos, com idades entre 18 e 65 anos, provenientes das cinco regiões geográficas brasileiras e subdivididos pelos níveis de ensino fundamental, médio e superior. Os resultados apontaram tamanhos do efeito entre médios e grandes na comparação entre os níveis de ensino fundamental e médio;  grande a muito grande na relação entre o ensino fundamental e o superior e; pequenos a médios entre os níveis médio e superior de ensino. Concluiu-se que as diferenças estatisticamente observadas, por meio das análises de variância e pos-hoc de Tukey refletem um efeito real quando se considera o impacto da variável nível de escolaridade no desempenho do teste. Entendeu-se que os estudos normativos do instrumento refletem um impacto real quando se considera a variável em estudo, devendo incluir o tamanho do efeito e seus respectivos intervalos de confiança.Universidade Federal do Ceará2022-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/epub+zipapplication/octet-streamapplication/xmlhttp://www.periodicos.ufc.br/psicologiaufc/article/view/7838210.36517/10.36517/revpsiufc.13.2.2022.9Journal of Psychology; Vol 13 No 2 (2022): V.13, N.2, 2022 (JULHO-DEZEMBRO); 122 - 138Revista de Psicologia; v. 13 n. 2 (2022): V.13, N.2, 2022 (JULHO-DEZEMBRO); 122 - 1382179-17400102-1222reponame:Revista de Psicologia (Fortaleza.
