Expert Answer
There is a generalised things of internal validity and external validity that can apply to the situation mentioned in the question. According to the question the systematic/controlled of measures of behavior also have the similar effect .
Internal Validity means how you are doing your experimenmts and whether it be removing confounding or not.Also it means the the changes that we are getting is because of change in independent variable not because of any other factor. The probable decrease in confounding increases the Internal validity.
Ways to increase the Internal Validity :
1) Keep a record all the other independent factors that can effect dependent factor.
2)Do your experiment on smaller scale before conducting for larger or real situation and check for any unpredicted change in experiment.
3)Make your experiment a standardised way and check if the result is for each event or participant is same or not.
External Validity refers the the result that we got after doing the experiment whether we can apply that result to te world or outside your studies or not. This is simply because the reason behind a particular study is t...
