Resumo Este artigo objetiva ilustrar a análise de outlier(s) aplicada aos cálculos bibliométricos. O Outlier é uma observação, elevada ou reduzida, em relação ao conjunto de dados. São três as causas possíveis para ocorrência de outlier: registro errado, o outlier provir de outra população, ou a medição do outlier ser correta, mas representar um evento raro. Assim, o outlier pode potencialmente produzir impacto nas abordagens de estudos bibliométricos. É importante identificar o outlier para a condução de análises alternativas, com ou sem a presença do outlier.

Abstract This article aims to illustrate the outlier analyses applied to bibliometrics analysis. Outlier is an observation that is unusually large or small relative to the data set. There are three possible causes to outlier: incorrect value; the outlier comes from another population, or that the measurement is correct, but represents a rare event. So, outlier can potentially have a deeper impact on the bibliometric study. It is important to identify outlier to at least to perform alternative analysis with or without the outlier.
