See which direction you want to go in your future work. Beijing Institute of Technology is an engineering college, which is more rational in statistics and pays more attention to the research of related mathematical theories. Central University of Finance and Economics is a financial college, and statistics tend to be applied economically. In fact, statistics is not very good for employment, and the economy is still used more. If you consider more employment, it is better to choose central finance and economics; If you want to study it in depth, I personally think Beijing Institute of Technology is better.
