Question

A researcher has observed that children who eat more sugar tend to show a higher level of activity than children who eat less sugar. However, the researcher suspects that the apparent relationship may be explained by the fact that some children have a higher rate of metabolism, which causes them to eat more and to be more active compared to children with a lower rate of metabolism who eat less and are less active. This is an example of the ____.

Answer 1

The correct answer is the third variable problem

A system of equations can be formed by several unknowns, but it will only be solved if the number of unknown terms is equal to the number of equations in the system. The systems with three variables can be solved through the processes already known and studied, substitution or addition.

Answer 2

Question Optons:

a) directionality problem

b) third-variable problem

c) extreneous variable problem

d) manipulation problem check

Answer: THIRD VARIABLE PROBLEM

Explanation: Third variable problem can be defined as a process whereby an apparent association between an exposure and an outcome is explained by another factor in which the third variable leads to a mistaken causal relationship between two others.  

The three variables here are, children; sugar; metabolism. Originally the research was linked to only the children and sugar then later on, a third variable, that lead to a mistaken casual relationship, metabolism came into place.
