It's not just income related because lower income students in schools without uniforms do better than students with similar incomes in schools with uniforms.
OP, I think it's great that you've suddenly decided to take an interest in statistics. It's good to understand the facts that get presented to us on a regular basis and learn to interpret them a bit more cannily than the average bear. One thing you will learn in your study is that when you are considering something like "student performance" it's helpful to be really specific about what you mean. Do you mean "higher test scores"? Do you mean "fewer disciplinary actions"? Do you mean "better educational outcomes" and if so, over what time period?
It's also helpful to think about data that may disprove your hypothesis. If you are suggesting, for example, that students who wear uniforms have poor educational outcomes overall, and that the uniform is directly responsible for those outcomes, consider that professional athletes, members of the military, and many other professions wear "uniforms." In some cases, the uniform is a good delineator of group membership - an athlete whose team wears red and white can generally recognize other players wearing that uniform as being on their team, and players wearing blue and yellow as not being on that team. There is also the other side of that particular argument, which could be made by saying that criminal gangs also use uniforms to distinguish between members and non-members. Crips wore/wear blue, for example, while Bloods wore/wear red.
You also have the issue of dress codes, which are less rigidly enforced uniforms. The dress codes at DC private schools, for example, may actually be stricter than the uniform policy at my DD's Title 1 school. Lawyers tend to wear suits, which is certainly a kind of uniform. When we are invited to a wedding, we do not tend to wear jeans and flip flops, because we understand, socially, that a certain type of attire is required for certain situations.
My point is that a lot of things are correlated with poor educational outcomes, whether those be in the form of test scores or discipline, and if you want your statement to carry any actual meaning, you should probably be more specific about the strength of the correlation, rather than simply its negative orientation. Are uniforms more strongly correlated with poor educational outcomes, for example, than family educational history? Than income level? Than race? Than geographic location?
