What would a control be for a experiment to see whether fertilizer helps a plant grow?
answer: compare a plant not given fertilizer to a plant given fertilizer..
Why must controls such as plants given water only be used in the fertilizer experiment described in the study guided?
to elliminate soures of error
Why must controls be used in fertilizer experiment?
to elliminate soures of error
Can a plant grow in salt water or distilled water?
Some plants do benifit from salt in the water but you can experiment with distilled water for your plants.
Example of control group?
The control group is the one that is not manipulated in any way. Suppose we are testing the effect of studying on test scores. The group that did not study would be the control group. The group that did study would be the experimental group.
What is an independemt variable?
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
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 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.
What is a real life example of independent variable?
A real life example of a variable is If one were to measure the influence of different quantities of fertilizer on plant growth, the independent variable would be the amount of fertilizer used (the changing factor of the experiment).hahahehe Yahoo answeres.com
What is the independent variables of fertilizer to plants?
How much fertilizer will be used and what kind of fertilizer.
What is a level of treatment?
It's the level of how much you do in the experiment. Such as when you test a fertilizer, you would do a control test with no cups of fertilizer, and a couple more with 1 cup, 2 cups, 5, 10 50 or whatever you choose.
Why must such as plants given water only be used in the fertilizer experiment?
Why must controls (such as plants given water only) be used in the fertilizer experiment
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.
What would a control be for an experiment to see whether fertilizer helps a plant to grow?
answer: compare a plant not given fertilizer to a plant given fertilizer..
What would a control be for a experiment to see whether fertilizer helps a plant grow?
answer: compare a plant not given fertilizer to a plant given fertilizer..
If one plant receives extra water and the other receives extra fertilizer is these experiment controlled or not?
Not. A controlled experiment is one where there is a control - in this case what is needed is a plant which receives no extra fertilizer or water.
Why must controls (such as plants given water only) be used in the fertilizer experiment?
to have something to compare with the growth of fertilized plants.
