What is the soundness of conclusions can be drawn from an experiment?

After the scientist makes a hypothesis they perform a to collect data?
the answer is the scientist designs a scientific inquiry

Can a study have internal validity but not external validity?
Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.

What options does a scientist have if experiment does not support hypothesis?
a scientist can do another experiment or change their hypothesis.

A scientist performs an experiment The results of the experiment disagree with a scientific theory The scientist repeats the experiment several times and gets the same results The scientist then?
The scientific theory should be changed.
A scientist does an experiment The results of the experiment disagree with a major scientific theory What should the scientist do?
Analyze the experiment to decide whether the results were flawed.
How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
