Carlos is trying to figure out the best place to put his router in order to het the best signal. Which is not an independent variable?

A) distance from the wall
B) signal strength at the computer
C) the number of walls between the router and computer
D) the number of devices on the router

Respuesta :

Answer: B) signal strength at the computer

Explanation:

The independent variable in the experimental setup can be changed or manipulated so as to know it's influence over the dependent variable which is the outcome of the experiment.

Here, the signal strength of the computer is the dependent variable which is obtained due to the position of the router which is the independent variable. The distance from the wall, the number of walls between the router and computer and the number of devices on the router all are the examples of the independent variable.

In an experiment, we can define 3 types of variables, the independent variable, which is the one that we can change. The dependent variable, which is the one that changes in response to the change in the independent variable, and the fixed variables, that are other variables that also can affect the dependent variable, and this is why we need to fix them.

With this in mind, we will see that the correct options are:

B) Signal strength at the computer

D) The number of devices on the router.

Now we can think on the experiment as:

Carlos wants to find the best position of the router to have a better signal, then the thing that he changes is the position of the router, thus, the independent variables are all of these that have a direct relation with the position of the router.

From the options, the only ones that are not independent variables are:

B) Signal strength at the computer (this is the dependent variable)

D) The number of devices on the router.
