An attempt is made in this work to compare the quality of laboratories with regard to their analytical results and also the comparison of the quality of methods of analysis with regard to their sensitivity to various soil samples analyzed during an IAEA-WEPAL organized proficiency test in 2010 which Nigeria is a signatory to. The methods used for the comparison include: the Youden plot and the ranking test. These statistical methods were used to analyze the results obtained from participant laboratories in which the determination of the content of Al, Fe, and N on four soil samples namely Braunerde Clay (ID 872), Sandy Soil (ID 995), Clay (ID 883) and Sandy-Clay Soil (ID 958) were considered due to the fact that most of the participant laboratories on the pr... view more»
