      B.pharmacy 8th semester Biostatistics BP801T according to AKTU AND PCI SYALLABUS.    Today topic is blocking and confounding Blocking Technique has been utilized to handle Randomized Complete Block Design in the earlier Module.  As the 2k design is primarily used to screen factors/variables, often a very large number of experimental units are required to complete even one full replication. For an example, 26 design with six variables requires 64 experimental units to complete one full replication. In the 2k design of experiment, blocking technique is used when enough homogenous experimental units are not available.  Different batches do not necessarily mean non-homogeneity all the time. However, keeping track of the batch numbers as blocks (the statistical term) would provide an opportunity, if in case there is non-homogeneity from batch to batch.  Therefore, a block is defined by a homogenous large unit, including, raw materials, areas, pla...
