Independent variable
To achieve internal validity, a researcher must design and conduct experiments where only the independent variable can be the cause of the results.
<h3>What are internal and external validity?</h3>
The degree to which a study shows a reliable cause-and-effect relationship between a therapy and a result is known as internal validity. Internal validity also shows that a particular investigation enables the exclusion of competing hypotheses for a finding. Internal validity is not a binary term, either yes or no. Instead, we evaluate how confident we can be in a study's conclusions depending on whether it avoids pitfalls that could cast doubt on the results.
The term external validity describes how effectively the results of a study should be extrapolated to other contexts. In other words, the generalizability of the results is the subject of this form of validity. For instance, are the results generalizable to different populations, environments, circumstances, and eras? Transferability is a different word that describes external validity and a qualitative research design. Whether results apply other circumstances with similar characteristics is referred to as transferability.

Answer:
ARGUMENTS FOR AND AGAINST ANIMAL EXPERIMENTATION
For
1. Animals have always been used for experiments that are considered dangerous for humans, e.g lab rats.
This is necessary as some procedures are considered too dangerous for a human to undergo, and therefore, an animal is used to test the process.
2. Animals cannot talk, therefore, have no rights.
Animals, though living, do not have and enjoy the same rights that humans do according to the Universal Declaration of Human Rights. This makes it possible to subject them to experiments because no rights are being infringed upon.
Against
1. It is unethical and inhumane to use animals for experiments
Animals have feelings and as such should not be used for unsafe experiments. The practise is inhuman and unethical as it is done without the consent of the animal.
2. Animals are living things and so they have rights.
Animals are living and such should be considered to have rights just as humans do and it would be wrong for any scientist to get any animal of his choice to perform experiments.
