How do you improve the accuracy of the experiment impact of a jet?
it is by repeating the experiment a few times which make the results more reliable
What change would make the data from this experiment more reliable?
i think to make i more reliable i would add more stuff to it
What happens when scientist have to redo an experiment?
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
What is the amount of error when using a stopwatch in the simple pendulum experiment and by repeating the amount of swings when timing does this make it more accurate?
no.
What two reasons make otherwise good scientist ignore the more scientifically valid rapid decay theory?
Look for the answer in your book. Its there.
How do you make a test more valid?
In a valid experiment all the variables are kept the same apart from those being investigated.
Why a control needed in a valid experiment?
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
What makes a valid experiment?
A valid experiment is characterized by a clear hypothesis, a control group for comparison, random assignment of participants, and the ability to replicate the results. It should also have ethical considerations and controls in place to minimize bias and confounding variables.
The analysis of a data gathered during a particular experiment is necessary in order to?
Draw a valid conclusion for that experiment.
To be valid an experiment must not include?
To be valid, an experiment must not include bias, confounding variables, or unreliable measures in order to accurately assess the cause-and-effect relationship between variables.
What is the definition of Valid Experiment?
cheese
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.
Why do you think its important to repeat an experiment?
to make the experiment more reliable
What questions should Emma ask the student to find out if the student's conclusion was valid?
I.What types of plants were used in the experiment?II.What was the experiment's control? III.Was the experiment repeated more than once?
How do you make an accurate experiment?
To make an experiment more accurate you would have to repeat the experiment 3-5 more times to make it reliable and also you would do what Liverpool college do and compare the answers with other people in the class, community or teacher.
To be a valid scientific experiment the results must be?
Repeatable
What is the minimum number of trials for an experiment to be valid?
3
