What is confounding in experimental design?
The confounding design is known to be a type of a design where some treatment effects (such as the main or interactions effect) are said to be approximated by the same linear association of the experimental observations as some blocking effects.
Note that an hypothesis is said to be a kind of preplanned or proposed explanation for any kind of a phenomenon that occurs in an experiment.

Select the correct answer from each drop-down menu.
When Raymond observes certain natural phenomena, he often forms ideas about their causes and effects. Suppose that Raymond surmises that leaves change color in autumn due to scarcity of sunlight. In order to test whether his idea is accurate, he must first construct a falsifiable [THEORY/LAW/HYPOTHESIS] that defines a clear relationship between two variables. Raymond's next step is to [DESIGN AN EXPERIMENT/COMPLETE MATHEMATICAL CALCULATIONS/PROPOSE AND EXPLANATION] that would isolate and test the relationship between the two variables. This task can be pretty daunting because Raymond will need to identify and eliminate any [CONFOUNDING/DEPENDENT/INDEPENDENT] variables that could confuse test results.
