For data analysis, if you find it really difficult, you can study it separately. The first is to improve the reading ability of materials and find them accurately and quickly. This can be practiced by taking more data analysis questions. When you see the problem, you can only find the data related to solving the problem, and you don't need to calculate it. After this breakthrough, we can cultivate the ability to extract information. First, you can master some fast calculation methods, and then you can take some data for training. I believe that the breakthrough in these two aspects, coupled with a comprehensive grasp of some statistical terms and corresponding calculation formulas, will be a good breakthrough in data analysis. Compared with simplifying complex problems and solving them in blocks, if this learning method is adapted to this method, it will certainly get good results.
