What else can I help you with?
What statements about controlled experiments are true?
I am not a scientist, but offer my perspective as a popular consumer of science-related information. Each of them may be considered true depending on context or on how terms are defined, but the one that is most true is "Controlled experiements produce valid data" Controlled experiments are those in which as many factors as possible are accounted for in their design, so that results are less likely to be caused by some anomaly or by some variable other than the one(s) being studied."Controlled data produces valid experiments" could be at least indirectly true, since good data will help determine how and to what extent variables will be manipulated by the researchers. But in most research scenarios it is not the data itself that is acted upon in the experiment, it is physical processes-- the ones that will eventually yield data. A possible exception would be computer or other information related science, where actual data may in fact be subjected to various procedures."Valid experiments produce controlled data" could be true if you think of the word 'controlled' in a certain way. Ideally, the data coming from an experiment is not controlled by the researchers, or at least it shouldn't be. The data should reflect the natural interaction(s) of the variable(s) being studied. Otherwise the research is meaningless, or worse, falsified. But you might think of the outcome data as being, in a way, controlled by the variable(s) being studied.
What is an experiment in which only one factor is allowed to vary?
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
Does scientific method have to be controlled in order to be valid?
No, the scientific method can be uncontrolled to for it to be valid.
What are the steps when doing experimental research?
Form a hypothesisDetermine what variables can be varied that should or should not influence results when varied if the hypothesis is correct and if it is incorrectdesign experiments where those variables can be controlled for, and the results measureddetermine the a statistically valid method for running the experiments while controlling for different variablesrun the experiments, recording the resulting measurements and observationsanalyze the results and compare to the results predicted by the theory.
Why is hypothesis is discarded as a valid hypothesis?
when results from the experiments repeatedly fail to support the hypothesis.

In biology what is a variable?
In biology, a variable is any factor or condition that can change or be controlled in an experiment. Variables can be independent (the factor being tested), dependent (the outcome being measured), or controlled (kept constant for comparison). Understanding and controlling variables is critical for designing valid experiments and drawing accurate conclusions.
Why do you test hypothesis?
So you know whether it is valid or not. If it isn't modify your hypothesis to fit the results of your experiments.
Why does science have problem with superstition?
Science relies on repeatable, redundant results from experiments in order to consider it valid.
What is the difference between a valid test and a reliable test?
Reliable indicates that each time the experiment is conducted, the same results are obtained (accuracy). Valid indicates the experiment (or test) has controlled variables and used an appropriate method/model.
What are controlled drugs?
So-called "controlled substances" are narcotic and narcotic-type drugs strictly controlled by law and, if availalbe at all, are only available with a valid/legal prescription.
Why do experiments need to be repeated to be valid?
So it becomes a fair test and you can make sure you didn't make any mistakes :)
Can bugs effect science experiments?
Bugs can effect science experiments. If the experiment does not involve bugs yet they end up near or contained within a science experiment then the experiment is no longer valid and has to be repeated.
