What effect does the amount of fertilizer have on the growth of a plant what would be the independent variable?

The dependent variable is the growth that depends upon (or results from) the application of fertilizer. The independent variable is the fertilizer itself.

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 independent variable of a homemade lava lamp?
The independent variable of a homemade lava lamp experiment could be the type or amount of oil used, the type or amount of water used, or the type or amount of effervescent tablets used. This variable is manipulated by the experimenter to observe its effect on the outcome of the lava lamp's behavior.
What is the independent variable for sugar?
The independent variable for sugar could be the amount of sugar (in grams or teaspoons) added to a food or drink item. This variable is what the researcher manipulates or controls in an experiment to observe its effect on the outcome.
What is the variable being studied in this experiment?
The variable being studied in this experiment is the independent variable, which is the factor that is being manipulated or changed by the researcher to observe its effect on the dependent variable.
The one variable that is purposely changed to test a hypothesis is?
The independent variable is the one variable that is purposely changed in an experiment to test a hypothesis. It is manipulated by the researcher to observe its effect on the dependent variable.
What is a independent vairable?
The object you are testing in a hypothesisThe Independant or manipulated variable is what 'I' or you are changing....if you are measuring the effect of fertilizer on plant height, the Independant variable is the presence/absence of fertilizer.
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.
Dependent and independent variables in biology?
In biology, the dependent variable is the factor being measured or tested in an experiment, and its value depends on the independent variable. The independent variable is the factor that is manipulated or controlled by the researcher to observe its effect on the dependent variable. For example, if studying the effect of different fertilizer amounts (independent variable) on plant growth, the plant growth measurements would be the dependent variable.
What are the scientific variables and what do they mean?
In an experiment, the independent variable is the variable that is manipulated, for example plant fertilizer. The dependent variable is what is observed and measured as a result of the independent variable, for example plant height. Controlled variables are factors that are kept constant for the entire experiment, such as temperature and moisture, so that the observed results are due only to the independent variable. So in an experiment measuring the effect of fertilizer on plant growth, the independent variable would be the fertilizer, the independent variable would be the height measured at specific intervals, and the controlled variable of temperature and moisture would be kept the same for both groups.
What are science variables?
There are three different types of variables in science.Independent Variable: The one you choose to change. Or it is the cause of the change in the dependent variable. (Ex: amount/type of Fertilizer)Dependent Variable: The one you choose to observe. The one that receives the effect of the independent variable. (Ex: Plant ; the one you'll use with the fertilizer)Controlled Variables (Usually more than one): The ones that remain the same throughout the experiment.
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 is the independent variable of a homemade lava lamp?
The independent variable of a homemade lava lamp experiment could be the type or amount of oil used, the type or amount of water used, or the type or amount of effervescent tablets used. This variable is manipulated by the experimenter to observe its effect on the outcome of the lava lamp's behavior.
What is a controlable variable?
A variable which can be controlled by some other variables or some other parameters is known as controlled variable. A controlled variable is something that can be changed by the experimenter. It is also known as the independent variable. It is something that gives a measure by which to gauge everything else by. For example, if you were testing the effectiveness of a plant fertilizer the "control" would be a plant that is given no fertilizer at all. A controlled variable is the variable that stays the same through out the experiment meaning no changes to it.
What is the independent variable for sugar?
The independent variable for sugar could be the amount of sugar (in grams or teaspoons) added to a food or drink item. This variable is what the researcher manipulates or controls in an experiment to observe its effect on the outcome.
What variable causes an effect?
The independent variable is the variable that is changed or manipulated by the researcher and is hypothesized to cause an effect on the dependent variable. The dependent variable is the variable that is measured in response to the changes in the independent variable.
How does independent variable effect the radish germination?
The independent variable in an experiment could be factors such as light, temperature, or water levels. By manipulating the independent variable, such as changing the amount of light or water given to the radish seeds, you can observe how it affects their germination rate. Each independent variable can have a different effect on radish germination.
Is cause the independent variable?
Not necessarily. The independent variable may have no effect at all.
