Question

Cocoa plant type 1 yielded 155 bushels per acre last year at a research farm. This year,
cocoa plant type 2, planted in the same location, yielded only 123 bushels per acre and
there was a major freeze. The researchers do not know whether the difference is the
result of the superiority of type 1 or the freeze. What is this an example of? (4 points)
- Bias
- Confounding variable
- Matched-pairs desighs
- The placebo effect
- Replication

Answer 1

The confounding variable, often described as a confounder or confusing factor, is a dimension in studies looking at a possible causation link, and further calculation can be defined as follows:

• It has connected both to the study's apparent cause and its ostensible impact.
• It can be difficult to differentiate between both the genuine relationship between the independent variable and the effect of a contextual factor.
• It is an external factor that alters the impact of variables to utilized to sway the findings of an experiment.

Therefore, the final answer is "Confounding variable".
