Background: Effect size reporting what is the correlation coefficient of the linear fit interpreting practices have been extensively recommended in academic journals when analyzing primary outcomes of all empirical studies.

Accordingly, the sample squared multiple correlation coefficient is the commonly reported what does associative law mean in maths of association index in practical applications of multiple linear regression. Method: This paper examines the sample size procedures proposed by Bonett and Wright for precise interval estimation of the squared multiple correlation coefficient.

Results: The simulation results showed that their simple method coorrelation attaining the desired precision of expected width provides satisfactory results only when sample sizes are large. Moreover, the suggested sample size formula for achieving the designated assurance probability is inaccurate and problematic. Conclusions: According to these findings, their sample size procedures are not recommended. Resultados: el resultado de esta simulación señala que su método ia para alcanzar la deseada precisión de la amplitud esperada proporciona el resultado satisfactorio solamente cuando el tamaño de la muestra sea extensivo.

Conclusiones: de acuerdo con estos descubrimientos, no se recomienda el procedimiento del tamaño de la muestra. Psicothema,
