Completely Randomized Design (CRD)

 COMPLETELY RANDOMIZED DESIGN

1. A Set Of Data Involving Four Tropical Feed Stuffs A, B, C And D Tried To 20 Chicks Are Treated Alike In All Respects Except The Feeding Treatments and each feeding treatment is given to 5 chicks. Analyse the data.

Feed	Gain in Weight
A	55	49	42	21	52
B	61	112	30	89	63
C	42	97	81	95	92
D	169	137	169	85	154

2. For testing the variety effect in a completely randomized experiment, the data (the yield of barley in grams) are as shown in the following table. Perform the analysis of variance.
