How many variables do you need in a science experiment?
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
Is water a variable?
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.
What kind of variable is part of the experiment that is affected by the independent variable?
Dependent Variable the independent variable is the one you change to get the dependent variable. The control group is the thing that you leave the same throughout your experiment. Hint: You don't want too many independent variables, it will mess up the experiment.
Are there independent or dependent variables in qualitative research?
i want to know the role of variables of the qualitative design
What are the 3 scientific variables?
The Independent Variable : It is the ONE thing you plan to be different in the experiment. You decide on what is going to be different BEFORE doing the experiment. Dependent Variable or Outcome Variable : It is the result you compare of measure in the experiment. Controlled Variable : This is the part of the experiment that you DO NOT CHANGE. This is what STAYS THE SAME.
How do you pick out independent variables and dependent variables?
An Independent variable is what you control; you decide the focus of your experiment and what you control on the independent variable. Dependent variable is what you want to look at or find results for; you decide what you want to see from manipulating your independent variable.
How many variables are supposed to be in a science experiment?
Most science experiments will have two independent variables. Fundamentally, an experiment will want as few variables as possible for better results.
What are Confounding Variables?
In any experiment there are many kinds of variables that will effect the experiment. The independent variable is the manipulation for the experiment and the dependent variable is the measure you take from that experiment. Confounding variables are things in which have an effect on the dependent variable, but were taken into account in the experimental design. For example, you want to know if Drug X has an effect on causing sleep. The experimenter must take care to design the experiment so that he can be very sure that the subjects in the study fell asleep because of the influence of his Drug X, and that the sleepiness was not caused by other factors. Those other factors would be confounding variables.

How many variables does a controlled experiment test?
As many as you need. You can't change more than one if you want accurate results.
What have you learned about variables?
1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.

How many variables do you test within one experiment?
Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.
What affect does salt to freezing point hypothesis indipendent and dependent variable?
An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.
