For finding exactly where the differences exist, we proceed to run Scheffe’s Test!! N Group Means to be used later Within Degree of Freedom DFw Within Group Variance MSw to be used laterĩ Calculation of LSD (Lease Significant Difference) For Group 1 vs Group 2 Please find any significant different increase of weight among the 4 groups.ĥ In Excel with ‘Analysis ToolPak’ Add-In activated, click Data, Data Analysis :-Ħ Choose ‘Anova: Single Factor’ = One-way Anova However, some chickens have died during the experiment, especially in groups with higher dosage. Completely Randomized Design Unequal Sample SizeĪn experiment with Completely Randomized Design has been started with 10 equal weight chickens in each group of Treatment A (Control), Treatment B, Treatment C and Treatment D, with increasing dosage of a new drug that might increase growing rate. But the chance of committing Type I error - It can be used in either Equal or Unequal Sample size conditionsĤ e.g. (Post Hoc = unplanned before experiment) It is the most ‘sensitive’ Post Hoc Test and most unlikely to miss sign. 1 Running Fisher’s LSD Multiple Comparison Test in Excelįor finding Inter-Groups Differences after getting significant results in overall ANOVA testĢ Fisher’s LSD Test It is also a popular Post Hoc Test.
