I need help getting an example of a data set that is suitable for the question below, for economics

For this Data exercise you need to do the following (1) Go to the internet and gather data that has two variables that you believe are related to each other. One should be the dependent variable that you are trying to explain and the other should be the independent variable that does the explaining. You need to have at least 50 observations but more observations are better (i.e. don't truncate a longer data set to only have 50 observations). Your project should not be the same as anyone else's in the class (if you work by yourself this should not be an issue). You should also not use a data set that has been put together for you from a textbook
