Question
Consider a vacuum metallization chamber. It could be used for decorating parts, we have a problem with the contamination in the room. Currently we believe part of our reason for this is that we have too many people in the room. We could base this as an analysis where the dependent variable is the contamination levels and products during a run. The independent variable would be the number of operators allocated to the room for the production run. This would be in observable experience experiment that could possibly be changed into a designed experiment in this example to set factors we could separate this is less than 12, between 13-18 and above 18 which would be the factors or all levels. The experimental units for this would be contamination particles, in the room. Another potential experimental unit could be the scrapped parts from contamination.State whether this observable experiment could become a designed experiment.

Explanation / Answer
As we have observed in the experiment that contamination levels are dependent on the no. of operators in the room. Under a design experiment, we put some conditions and see whether there is variation in the experiment unit. We could design an experiment in the following manner:
Three sets of conditions will be taken which is the independent variable (no. of operators):
1. No. of operators less than 12
2. No. of operators between 13-18
3. No. of operators above 18
We will record the experiment unit which is the contamination particles by putting the above conditions in a table. No. of observations must be good. Hence, variation between the sets will be determined by performing a test afterwards.
