Answer
A randomized design is used to test the effect of temperature on battery voltage. In the design, the batteries are divided into three groups and exposed to the temperatures of randomly.
The engineers want to test the effect of temperature on the voltage of the batteries. The batteries are divided into three groups and exposed to different temperatures. Three different temperatures of are randomly assigned to the groups of batteries. So, the experimental design can be considered as a randomized design.
Work Step by Step
In the above diagram, there are three randomized groups. Each group goes through a particular temperature that is randomly assigned. The voltage of the batteries is recorded for the study.
