Description: This article provides information on the effectiveness of various laundry products, such as liquid stain remover. An experiment with coffee stains was done and it was assessed if there exists significant differences between these products. With the variance analysis done, we can conclude that there is evidence to confirm that the liquid stain removers are just as effective, at 5% significance. A block design was selected using the fabric type as a controlled variable. However, upon analyzing this block criterion in the results, it can suggest that, for future experiments, it is not necessary to lay the block and the randomized complete design can be used.
Este artículo proporciona información sobre la efectividad de los diferentes productos de lavandería, como son los líquidos quita manchas. Se desarrolló un experimento con manchas de café y se evaluó si existe diferencia significativa entre estos productos. Con el análisis de varianza realizado podemos concluir que existe evidencia para confirmar que los líquidos quita manchas tienen la misma efectividad al 5% de significancia. Se seleccionó un diseño de bloques utilizando como criterio el tipo de tela, sin embargo, al analizar este criterio de bloque en los resultados, se puede recomendar que para próximos experimentos, no es necesario bloquear y se puede utilizar un diseño completo al azar.
