WebActivity: Answer Key: This activity walks students through three different experimental designs, in increasing complexity. Completely randomized design. Block design. Matched pairs design. Notice that the matched pairs design is really just a fancy version of a block design, where each block is of size 2 (two students paired with similar GPAs). Webvalue is required for significant difference among treatments. The paired sample experiment discussed in Chapter 6 is the simplest case of using the concept of blocking, where pairs are blocks. 8.1 Randomized Complete Block Design Without Subsamples In animal studies, to achieve the uniformity within blocks, animals may be classified on

Web1. Control. 2. Replication. 3. Randomization. Example: In this design we would randomly select 60 students and randomly split them into two groups with 30 each. One group does not take the practice exam, while the other does. We have the two groups then take the actual exam and we compare results.
