Question

Denise conducts a study to find out which of three subway routes gets her to work in the shortest amount of time. in denise's experiment, the independent variable is the __________ , and the dependent variable is the __________ .

Answer 1

Independent variable : Subway routes

Dependent variable : Time

Step-by-step explanation:

Dependent variable are outputs that are derived from an altered input . In other words the outcome depends on adjustment to a set of independent variable. In research and experiments , the variable output is always being tested to see how it will react to independent variable

Independent variable are the sets of variable that are manipulated in an experiment in order to know its effect on the variables that rely on it .Any changes to the independent variable will definitely affect the variables that depend on it .

In the question , we can see that the amount of time is dependent on the subway routes followed to work. Any changes to the route will affect the time in either ways.

Answer 2

The independent variable is the subway routes it is because an independent variable is a type of variable that can stand alone without being changed by other variables.
The dependent variable is the shortest amount of time, it is because the result is dependent the factors such as the subway routes, if whether which of three can get her to work in the shortest amount of time.
