Richard's developmental psychology class finds a positive correlation between the height and weight of the class members. A class member asks, "What does early nutrition have to do with this finding?" This class member has stumbled onto what issue associated with correlations?

The third-variable problem

Explanation:

The third variable problem refers to the fact that a causal relationship between two variables cannot be inferred from the naturally occurring correlation between them because of the ever present possibility of third variable correlation.

Also, the third variable is the entire cause of the correlation between the two variables of interest and there's no causal relationship between them at all but the key difference between experiments and correlational studies concerns the variable that is thought to be the cause.

the correct answer is individualism and exchange. at this stage, children begin to question the rules, because they can see that there is more than one side to them. different individuals have different viewpoints. they won't be able to reach this stage because of ignorance, a lack of ethics or personal biases. that is because people with that characteristiscs are not able to distinguish what is good or what is bad and they can't pursue their individual interests.
