An independent variable is what you control. So in this case the independent variable would be how you're killing the bacteria (different solutions of bleach, different temperatures, different wavelengths of light, etc). The dependent variable is the variable you are looking for a change in, in this case it would be how many bacteria die.
What else can I help you with?
Does the independent or dependent variable change?
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
What type of a variable is an experimental controls?
independent variable
Is the independent variable the one that does not change?
No, as the name Variable implies, it can and does change. Since it is 'Independent' its change is not a direct effect of the change of any other Variable. Additionally, the independent variable depends on the dependent variable.
The factor being measure in an experiment?
The dependent variable is monitored as the independent variable is changed. One is testing the effect of the independent variable on the dependent variable (ie effect of dissolved HClO on pH).
In an experimental investigation the variable that the researcher changes or manipulates in order to see its effects is called the?
Independent variable, is variable that the experimenter manipulates
The dependent responding variable in this experiment is?
The dependent variable in an experiment is the variable that is measured to determine the effect of the independent variable. It is the outcome or result that is being studied to see how it changes in response to the manipulation of the independent variable.
A doctor grows some bacteria in a petri dish for several days which is the independent variable in this situation?
number of bacteria in the dish
What was the independent variable in Pasteur's experiment?
The independent variable in Pasteur's experiment was the type of flask used to hold the broth. He tested both open-topped flasks and swan-necked flasks to determine which allowed the growth of microorganisms.
What is the manipulating variable the dependent variable or the independent variable?
The independent variable.
Independent and independent variable in sentence?
Changes in the independent variable are independent of changes in any other variable,
What is the diffrence between dependent variable and 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.
What is the test variable (independent variable) in the experiment?
The independent variable.
Does the independent or dependent variable change?
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
What is the dependent and independent in a experiment?
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
Independent and dependent variable?
Math: Independent variable is what you change. Dependent variable is what you measure.
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.
What is a Factor that is deliberately changed in a experiment?
the anwer is a variable( the thng that will change over time in the experiment
