Design of Experiments Question
What do you understand by 'Design of an Experiment'? Physicians depend on laboratory test results when managing medical problems such as diabetes or epilepsy. In a uniformity test of glucose tolerance, three different laboratories were sent $n_t = 5$ identical blood samples from a person who had drunk 50 mg of glucose dissolved in water. The laboratory results are listed below: Do data indicate a difference in the average readings for three laboratories? Use $\alpha = 0.05$.
| Lab 1 | Lab 2 | Lab 3 |
|---|---|---|
| 12.1 | 9.3 | 10.0 |
| 11.7 | 11.1 | 10.5 |
| 10.9 | 10.7 | 10.1 |
| 10.2 | 10.9 | 11.0 |
| 10.6 | 9.0 | 10.4 |

Design of an experiment is the systematic planning of an investigation so that valid, unbiased, and reliable conclusions can be drawn from collected data. It specifies how treatments are allocated to experimental units, how many replications are used, and how to control extraneous variation. Fish...
