Corn variety 1 and variety 2 have been planed at the same place.
Amount of corns yielded by variety 1 and variety 2 are 140 and 110 bushels per acre.

Confounding occurs in an experiment when it is not possible for an experimenter to separate the effects of two variables. Here, it is not possible to differentiate the effect of two variables weather and variety which depicts that provided case is an instance of confounding.
