The statement that correctly describes related variables is given as follows:
Two variables are related when a discernible pattern exists between them.
Two variables are said to be related if one variable can be written as a function of another, that is, the output variable can be written as a function of the input variable.
There are multiple relations between variables, such as linear, quadratic and exponential relations. What is common for all these relations is that a pattern exists between these variables, meaning that the third option gives the correct option.
The pattern is identified from a sample of observations of these two variables, in which it is verified how the dependent variable varies according to the independent variable.
