With reference to the Baumol/de Long controversy over the importance of the sample selection when verifying the convergence hypothesis, the paper concludes that the convergence results are conditioned by the joint consideration of the United States and Japan in the same country sample. The illustration of this result lays on the ó-convergence concept and uses the simple coefficient of variation as dispersion statistics. The database is the one provided by the OCDE regarding prices and estimates of constant purchasing power parity (base year 1990). In the Appendix, the results are compared with those obtained with an alternative source, the database supplied by Summers and Heston (Mark 5.6). Tomando como referente la polémica Baumol/de Long sobre la importancia de la selección de la muestra en la contrastación de la hipótesis de convergencia, el trabajo concluye que ésta se encuentra condicionada por la consideración conjunta de Estados Unidos y Japón en la muestra de países. La ilustración de este resultado descansa en el concepto de ó-convergencia y utiliza como estadístico de dispersión el coeficiente de variación simple. La base de datos es la proporcionada por la OCDE relativa a precios y paridad de poder de compra constantes (año base 1990). En el Anexo se comparan los resultados con los obtenidos utilizando, como fuente alternativa, la base de datos proporcionada por Summers y Heston (Mark 5.6).
