Not really, the better expiriment would be if you used both sides of t he penny and compare all of your trials.
A valid experiment is the one which is done on the basis of some facts and figures. The experiment which has a good statistical analysis is known to be valid experiment.step 3.
The results of an experiment are valid when they can be repeated by other scientists doing the same experiment.
To make an experiment valid you have to make sure that the experiments results answer the question that you first started from.
repeat the experiment at least three times to gain valid results :)
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.
a control group and statistical analysys of the resultsalso, to be considered valid, the results of a scientific experiment must be repeatable and still proven correct.
Draw a valid conclusion for that experiment.

when he or she's conclusion is right
There are several ways to make an experiment more valid. For example, one should always make any experiment repeatable, and they should conduct several trials before publishing results or coming to conclusions.
We only know that the results of an experiment are valid when other scientists are able to obtain the same (or equivalent) results. So, if the experiment is interesting, and it is carefully conducted and written up and published, other scientists will be interested in confirming your results.
Scientists use the data from an experiment to evaluate the hypothesis and draw a valid conclusion.
In a valid experiment all the variables are kept the same apart from those being investigated.
more than one variable
A hypothesis only becomes a valid argument after it has been proved. It is only a valid argument if there is proof (i.e. from an experiment).
A reliable experiment is one that can be proven or has been worked out several times giving valid or dependable results.
The experiment must be repeated a number of times and yield similar results.
No because if too many things change then the experiment will not be valid. So therefore, no a experiment cannot have more than one independent variable.
If the experiment is not reproducible, no one can perform the experiment independently to confirm the results.
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.
