Life is indeed largely experimental in nature; it is an ongoing process of learning what works and what doesn't, however, it is not true that the more experiments the better. There are some experiments that you should not be making. I was just commenting today, in reply to an earlier question, that you should not try cocaine just to find out what it is like, because that creates a possibility that you will become a cocaine addict, which is a very unhappy outcome, whereas if you never take cocaine, you will never become a cocaine addict. And there are many other things that you are better off not trying. What does it feel like to lose a finger? You don't really need to find out.

Why is an experiment better then an observational study?
An experiment allows for the researcher to manipulate variables and establish cause-and-effect relationships more effectively than an observational study. This control helps to minimize confounding variables and biases, making the results more reliable. Additionally, experiments often involve random assignment, which enhances the ability to draw conclusions about the relationships being studied.
What are the advantages of a thought experiment?
Thought experiments allow researchers to explore complex ideas or theories without the need for physical experimentation, providing insights that may not be possible through traditional methods. They can help refine hypotheses, challenge assumptions, and spark new avenues for research. Additionally, thought experiments are cost-effective and can be used to probe the limits of our understanding in a variety of fields.
Does the pavlov ring a bell?
No, "Pavlov" refers to Ivan Pavlov, a Russian physiologist known for his discovery of classical conditioning in his experiments with dogs. The ringing of a bell was a stimulus used in his experiments to evoke a conditioned response in the dogs.
What are the differences between field study and field experiment?
Field study involves observing and recording data in a natural setting without manipulating variables, while a field experiment involves manipulating variables to observe their effects in a natural setting. Field studies are more about observation and description, while field experiments are more about testing hypotheses through manipulation.
What are the advantages of E-prime in comparison with Presentation as experiment generators?
E-prime offers a more user-friendly interface and a wider range of customization options compared to Presentation. E-prime also has better technical support and resources available for troubleshooting and assistance. Additionally, E-prime is known for its compatibility with a variety of devices and systems.
What is the need to do more experiments called?
experiment
How can a scientific theory be changed by experiment?
Yes, it can if the experiments can add more data to make a real change. You would have to have others do the same experiments and agree with you.
After you reach a conclusion about an experiment you may find you need to experiment more.?
It is certainly possible. The conclusion from your experiment may prove to be tentative and you may need to design a better experiment to improve the reliability of the conclusion, or the experiment may suggest alternatives which you may wish to explore. Most of science is about that: an experiment leads to conclusions. Further experiments result in refinements to the conclusions and, occasionally, to the replacement of earlier theories with new models.
What did Edward Tilman's ecological experiments indicate?
Edward Tilman's ecological experiments indicated that species diversity plays a crucial role in ecosystem stability and productivity. His experiments showed that more diverse plant communities were better able to resist invasive species and recover from disturbances than less diverse communities. This suggests that biodiversity is vital for the resilience and functioning of ecosystems.
Why is it important to do an experiment more than one time?
We retest our experiments to insure accurate results and to compare with our original results.
Can a experiment have more than one independent variable?
yes it can I've done a few experiments that have had more than one independant variable.
What is true controlled experiments produce valid data valid experiments produce controlled data controlled data produces valid experiments?
With controlled experiments it is taken into consideration what possible variables there could be and it is taken into account when conducting the experiment. This would mean that controlled experiments would produce more valid data.
What is the difference between a manipulative experiment and a natural experiment?
A manipulative experiment involves actively manipulating variables to observe the effect on outcomes, while a natural experiment relies on naturally occurring variations in variables to study their impact. Manipulative experiments offer more control over variables but may lack external validity, while natural experiments provide insights into real-world situations but have limited control over variables.
How many variables do most experiments have in order to be sure of accuracy?
The amount of variables has nothing to do with the accuracy of the experiment. an experiment can have 1 variable or 100 or more and be perfectly accurate. i think the word you might've meant is tests? if so (lol) then the answer can vary upon the level of accuracy you're shooting for. experiments can have as little as 2-5 tests of as many as 100+. this answer also depends on how much time you have to complete the experiment.
What happens when scientist have to redo an experiment?
When scientists have to redo an experiment, it typically means that there were inconsistencies, errors, or unexpected results in the original experiment. Redoing the experiment allows them to troubleshoot, validate the findings, or ensure the reliability of the data before drawing conclusions. It is an essential part of the scientific process to confirm results and ensure accuracy.
Why is an experiment better then an observational study?
An experiment allows for the researcher to manipulate variables and establish cause-and-effect relationships more effectively than an observational study. This control helps to minimize confounding variables and biases, making the results more reliable. Additionally, experiments often involve random assignment, which enhances the ability to draw conclusions about the relationships being studied.
Why do scientists perform experiments after suggesting an answer to a problem?
An experiment is to carried out to analiysis the suggesting answer or we called it as a hypothesis is correct or not. This will give the scientist a more accurate answer towards the problem.
