Answer:Some individuals may be natural good at maths or may be just smart kids who are good with mathematics
Explanation:Some students may be intelligent or good at maths which means the shoe size will not be the cause of their quantification skills.
A confounding variable refers to another variable that you may have not take notice of but which is very likely to act on the variable you are trying to measure and make that change you are looking for , its an extra variable. It can mess up your experiment and give you result that are not caused by what your projected. They can assume a correlation that doesn't exist and insert bias in your study. For this reason you have to know these variable before you start your research or study in order to avoid them.
The answer is abnormal behavior. It is conduct that goes astray from what is normal and typical. The investigation of unusual conduct is called strange brain research.
Abnormal behavior is some of the time hard to characterize, for a few reasons. Above all else, individuals need to concur on what's typical. This can fluctuate broadly both inside and outside societies. For instance, when British pilgrims initially moved to America, they were accustomed to fencing area and raising animals on it. They had a smart thought of the contrast amongst open and private land.
Correlation research differs from experimental research by focusing on how variables d. are associated
<h3>What is Correlation Research?</h3>
This refers to the type of research that has to do with the establishment of causality and also the way some variables are associated.
Hence, we can see that this is very different from experimental research because experimental research has to do with the way variables are manipulated.
Therefore, option D is correct.
