Thank you a million times for providing me this source of information. I am beginning to gather more confidence that my MS Communication thesis will be a successful one. Now I have an equal and unilateral data source to compare the two candidates without compromising internal validity.
I mean I don't want to compromise internal validity. If I had to compare the two candidates, it's appropriate that the data source should be the same. Obtaining the data for the two candidates from different sources, for instance, may result in comparing an organic apple with a genetically modified one. This may undermine the internal validity of my data and the results arising from them.
