In the case of comparison between samples with unequal replications [n1 # n2\n# n3 # âË?â?¢Ã¢Ë?â?¢Ã¢Ë?â?¢ # nk], the statistician should use LSD (Least Significant Difference)\nmany times to achieve these comparisons, this method consumes more time\nand effort. The purpose of this research is to find out a new method to do easy\nand reliable comparison between population means when the experiment or\ndata involving different numbers of replications. In order to do this, a new\nformula was designed; the aim of this new formula is to develop the multiple\ncomparisons into one step instead of doing it with many steps that consume\nmore effort and time. In this work, the researcher used the mean of the replication\nnumber in the LDS formula instead of doing the calculation many\ntimes for each two means. The results of this study found that the new formula\ngive similar results for multiple comparisons with minimal effort. It was\nconcluded that the new formula (named Al-fahhamââ?¬â?¢s Formula) achieves the\nsame results with less time and efforts. It was recommended that Al-fahhamââ?¬â?¢s\nFormula can be approved in the statistical textbooks and procedures.
