Why must scientist control variables in their experiments?
An experiment is a simulation of complete or part of a real scenario in a controlled environment. We come to know of various outcomes of an experiment based on the values/degree of the variables in different quantity/quality. Unless the variables are controlled, experiment can go out of hand and sometimes become a real disaster.
What is the purpose of controlled variables in an experiments?
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
Why should only one variable at a time be changed in scientific experiments?
Doing so can enable you to pinpoint which independent variable had what effect on the dependent variable. If more that one variable is altered, there is no way of knowing which of them actually contributed to the change without doing further experimentation.
When writing a hypothesis using the if then format what variables come after if?
After it it's then and then because
What are the criteria for nomothetic causality?
1. The variables must be corelated. 2. The cause must come before the effect 3. Variables are nonspurious

Examples of independent variables?
Examples of independent variables include age, gender, temperature, amount of sunlight, type of treatment administered, and level of education. These variables are manipulated or selected by the researcher to observe their effect on the dependent variable in an experiment.
How do you come up with a hypothesis for a lab?
The lab would be used to test your hypothesis to whether or not you were correct. You would first want to form a hypothesis and then gather data to support or discredit your hypothesis. The hypothesis could be testing anything essentially.

The letters that come after the numbers in math are what?
Variables
What does variables mean in scientific terms?
A variable is something that can be changed.To vary is to change, and a variable is something that can change, particularly if it is a parameter of a scientific experiment. If you are, let us say, testing the effect that a drug has on rats, the most obvious variable would be the quantity of the drug which is administered to the rats. But there could be many other variables in this hypothetical experiment. Rats come in different sizes, ages, and genders; they can be overweight or underweight, they can be healthy or unhealthy. All of those are variables. You could alter the temperature of the environment in which the rats are being tested, or alter their diets; those are also variables. You would not necessarily want to devise different experiments to test the effects of all these variables; it is up to you to decide what interests you or what matters in terms of your research.
Do a research paper come before or after experiment?
After.
What does conclusion mean in science projects?
In a science experiment you create or come up with a hypothisys or in other words you come up with a sugjested outcome of the experiment that you are doing. The hypothisys is the experimenters best edjucated guess of what the outcome of the experiment is going to be. After making your hypothisys, the experiment is then preformed. After the experiment is finished and the data is collected and analysed the outcome of the experiment is known. At that point in time the experimenter knows weather their hypothesis was correct or not and they can come to a conclusion for that specific experiment with all the data found while doing the experiment. So in short the conclusion of an experiment is the final outcome of all the data collected from doing the experiment.
Why should only one variable at a time be changed in scientific experiments?
Doing so can enable you to pinpoint which independent variable had what effect on the dependent variable. If more that one variable is altered, there is no way of knowing which of them actually contributed to the change without doing further experimentation.
I can't come?
no u cant come anywhere
What year did the angel experiment come out?
It was published in 2005
What is it called when you want the results of your experiment to come out a certain way?
When someone wants the results of an experiment to come out a certain way, it is called experimenter bias or confirmation bias. This can lead to skewed results and undermine the validity of the experiment.
