Why is it importantthat all variables in an expiriment except for the independent variable are controlled?

Because otherwise it will not be possible to know whether observed variations in the dependent variable are due to one independent variable or another.


What is is an independent variable?

An independent variable is the variable that the scientist changes, and the dependent variables are the variables that the scientist doesn't control. So that would mean that the independent variable is typically the variable being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. The independent variable in a science experiment is the variable that you change on purpose. The independent variable is the variable that scientists manipulate in an experiment in order to determine its effect on a dependent variable. For example, if you wanted to see what affected frog deformities, you would set up an experiment where you would have frogs placed in the same environments as each other, except for one variable (independent) that is different. Let's say the control group gets exposed to all the same food, temperature, length of daylight, population density, etc., as the experimental group. The experimental group has the amount of UV exposure varied. The UV exposure (independent variable) would be used to determine its effects on frog deformities (dependent variable).


What is a easy definition of an independent variable?

Independent variables, namely a quantity change will not cause except the dependent variable other than the amount of change. Only by the independent variables to a physical quantities to express, it is by the function relation is correct The dependent variable, a quantity change will cause in addition to other than the dependent variable amount change. Put the dependent variables as independent variable, is to determine the relationship between a big physical quantities. Variables, it is to point to have no fixed value, can change the number Constant DuoZhong type, and every type is there is a data type, have integers, bytes, characters, floating point, enumeration, etc.


How would you differentiate independent variables from dependent variables?

The independent variable is the variable that you are curious about, and that you are going to change is some systematic way in an experiment to see what affect your changes make. What you check, to see if there are differences, is the dependent variable. According to your hypothesis, the values of the dependent variable will 'depend' on how you manipulate the independent variable. You want to know the effect of growing plants under different colors of light. You want to know how different colors of light (the variable you will manipulate) will affect plant growth (the dependent variable). You will want to use several controls, too. For example, if you try the above but you use several different kinds of plant, of different ages, in different soils and temperatures and different amounts of water, and different lengths of exposure to light (some sunlight, some 'full-spectrum lamps', etc) your experiment will be without value, except as a lesson in how not to do it!


What information do you need to know in order to write the equation of a line?

You need two variables. Make them x and y make y your dependent variable and x your independent variable. y=x1 this is a line y=4x1 this is a line y=4x1+3 this is a line y=x2 this is a curve y=x3 this is a curve make sure your x value has no power to it except 1 x=x1

Control and experimental groups are identical except for what?

The control and experimental groups differ in that the experimental group is exposed to the treatment or intervention being studied, while the control group is not. This allows researchers to isolate the effects of the treatment and compare it to a baseline.

Experiments that involve two tests that are identical except for one factor?

A controlled experiment involves two tests that are identical except for one factor, which is the independent variable. The effect of the independent variable is the one being tested.

What The one factor that differs between a control group and experimental group in a controlled experiment is the?

When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.


Independent variable in biology?

what you change and dependent variable is what you measure. :) Also, generally the independent variable goes on the x axis of any given graph, while the dependent goes on the y axis (except for specific types of graph characterized by their shape, such as rate of reaction graphs in chemistry)
