Question

Making a mathematical model

For each statement, write down a possible measurable input variable (independent variable) and a possible measurable output variable (dependent variable) to use for a mathematical model. Be as specific as possible for the variables. For each model: is it a cause and effect model?

A) "People who eat more pomegranates have larger houses."

B) "If you study hard, then you will do well in school."

C) "Those who lived near playgrounds as adults tend to be wealthier as adults."

Answer 1

A) People who eat more pomegranates have larger houses.

here independent variable may be number of pomegranates taken by a person and dependent variable is the area of the house the person owns

B)If you study hard then you will do well in school

here independent variable may be number of hours a person studies and dependent variable is the grade of the person in school exam

C) Those who lived near playgrounds as adults tend to be wealthier as adults

here independent variable is the distance of a person's house from a playground and the dependent variable may be bank balance of the person
