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.
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.
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.
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
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.
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.
the independent variable is If you throw the ball in the air ,then you will make it in the hoop the indepent variable is making the basket.
The independent variable.
Changes in the independent variable are independent of changes in any other variable,
The independent variable.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
Math: Independent variable is what you change. Dependent variable is what you measure.
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.
the anwer is a variable( the thng that will change over time in the experiment
