Question

ecorded D | Question 1 2 pts Suppose we use a person's dad's height to predict how short or tall the person will be. Suppose we decided to build a regression model to investigate if there is a relationship between these two variables. What should we use as the variables in the analysis? person's height dependent variable; dad's height-independent variable person's height, dad's height -both used as independent varilables person's height, dad's height -both used as dependent variables person's height - independent variable; dad's height dependent variable 2 pts Question 2 Suppose we use a person's dad's height to predict how will be by building a regression model to s dad's height to predict how short or investigate if a relation results ane as ship the two ex ists between t 6

Explanation / Answer

Since dad's height is used to predict person's height. So person's height is dependent on dad's height

So (A) is the right answer.

person height----Dependent Variable

Dad's Height-----Independent variable

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.The independent anddependent variables may be viewed in terms of cause and effect.

EXAMPLES:-

1. to test how the amount of sunlight affects the growth of radishes.

The independent variable is the amount of sunlight each plant receives and Dependent Variable is growth of radishes since growth of radishes is dependent on amount of sunlight.

2. to test the effect a gasoline additive has on gas mileage in a car,

the amount of additive per gallon is the independent variable and gas mileage is dependent variable since gas mileage is dependent on gasoline additive.
