Evaluation of Data

I definitely do not feel as though my data is a representation of the whole data pool of sexist and non-sexist advertisements, but I knew this all along as there are just too many. This is why it is going to be so hard to limit the variables and why I have been thinking about changing my idea. I am unsure of whether or not my data will be enough to test my hypothesis and write 1500 words on as my data is not particularly comparable. This is why I think it may be a good idea for me to find modern day equivalents to my research from the 1950s with modern day equivalents.
