There’s a positive correlation between the reading level of a child and how far they can jump. which variable is most likely the lurking variable that explains the correlation?

a. math level

b. number of siblings

c. age

d. number of pets

edit: for those in the future, the answer is c. age.

A lurking variable within statistics is one that is correlated to both the independent variable (a variable that is varied) and the dependent variable (a variable that is measured). A positive correlation between jumping distance and reading ability within a child is likely to be due to the child's age (answer c). 

What are the following algebraic equations. you need to post those if you want the answer
