I am learning about Experimental Design and I am confused with an example:
'The following chart displays the burning times of flares of two different type of torch design. The engineers are interested in comparing the mean burning times for the two types of design. Sample torches are tested one-at-a-time and the burning times of flares are recorded.
So The response is the burning time of flares, factor is the type of torch design, factor levels is type or type 2. I am confused for the treatments because there is no combination of the factor levels so is it possible this experimental design has no treatments or is this a case of a single treatment? Any help would be greatly appreciated!
