I assume that when we speak of air pollution, we are describing worsening or improving conditions over time. When time changes the pollution in the atmosphere changes. Thus pollution depends on time, making time the independent variable.

What is the variable you use during the part of an experiment that is being tested?

The variable being tested is called the independent variable. This is the variable that is deliberately changed by the experimenter to observe its effect on the dependent variable.


What does independent variable means?

When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.


What is the factor that changes in an experiment because of the manipulated variable?

REMEMBER:ReaDY MIX.....it helps me every time... MIX stands for Manipulated Independent X-axis......so the answer would be:Independent....hope this helps!:D Actually since the manipulated variable is independent the the factor that would change would be the responding variable which is the dependent variable so the answer would be: Dependent or Responding Variable


What affect does salt to freezing point hypothesis indipendent and dependent variable?

An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.


What 5 types of pollution?

The five types of pollution are air pollution, water pollution, soil pollution, noise pollution, and light pollution. Each type can have harmful effects on the environment, wildlife, and human health.

What is the diffrence between dependent variable and independent variable?

The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.

What is an independent variable in math?

An independent variable is a factor that doesn't rely on anything, unlike the dependent variable (which relies on the independent variable). The most common independent variable is time.
