In Alexander Fleming's experiment, the independent variable was the presence or absence of penicillium mold, which he introduced to the culture plates. The dependent variable was the growth or inhibition of bacterial colonies in the vicinity of the mold.

What is the independent and dependent groups of an controlled experiment?

In a controlled experiment, the independent variable is the variable that is deliberately changed or manipulated by the researcher to observe its effect on the dependent variable. The dependent variable is the variable that is observed and measured in response to changes in the independent variable. The independent variable is controlled by the researcher, while the dependent variable is the outcome that is measured.


What are the dependent variables in an experiment?

Dependent variables are the outcomes or responses that are measured to assess the effect of manipulating the independent variables. They depend on the changes made to the independent variables in the experiment.


Is the dependent variable or the responding variable the one being tested in an experiment?

The dependent variable is the one being tested in an experiment. It is the variable that is measured or observed to determine the effect of changes in the independent variable. The independent variable is manipulated to see its effect on the dependent variable.


In an experiment to determine the effect of different brands of fertilizer on the rate of plant growth what are the independent and dependent variables?

The independent variable in this experiment is the different brands of fertilizer being tested. The dependent variable is the rate of plant growth, which will be measured and influenced by the independent variable.


What is the dependent variable in Shakita's experiment?

The dependent variable in Shakita's experiment is the variable that is being measured or observed and is expected to be influenced by the independent variable. It represents the outcome or response in the experiment.

What is the difference of independent variable and a dependent variable?

An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,

The difference between the independent and dependent variables?

Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.


13 What is the relation between dependent and independent variables?

Independent variables are those that you change in an experiment. Dependent variables are the ones that you measure in an experiment. Dependent variables are influenced by the independent variables that you change, so they are dependent upon the independent variable. Generally, experiments should have only one independent variable.


How does the independent and a dependent variable compare in a experiment?

In an experiment, the independent variable is manipulated or controlled by the researcher, while the dependent variable is measured to see the effect of the independent variable. The independent variable is the cause, while the dependent variable is the effect. Changes in the independent variable are expected to cause changes in the dependent variable.


What are independent and dependent variables?

The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.


Differentiate independent variables from dependent variables?

In a controlled experiment, the Independent variable refers to the variable that is manipulated or altered. The dependent variable, meanwhile, is the result of the experiment.


What are the differences between independent and dependent variables?

Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
