In the past, some students have tried to use ridiculously small samples so you should give me an idea of your sample size. I would just like a brief statement of what you are planning to do your project on (e.g., a paragraph or two). You can later change your topic (but you should talk to me). Include an explanation of your data source. The data source should to be one that you have actually found and verified and not...
