Today, let’s talk about the data analysis process. Day 2 of #25DaysofDatawithDesola The truth is, there isn’t one single architecture uniformly followed by every data analysis expert. But, there are some shared fundamentals in every data analysis process. If you’re a data enthusiast, think of this process as a roadmap to guide you from messy datasets to meaningful insights. Here’s a step-by-step breakdown (???????????????? ???????? ?????? ???????????? ???????? ?????????????????? ???????????????????????? ?????????????????????? ????????????): ??. ??????: Before touching any data, ask yourself - what question am I trying to answer? Whether it’s analyzing sales performance or predicting the next pandemic, having a clear problem statement guides the entire process. ??. ???????????????: Once the problem is clear, gather the data you need.

Focus on clarity and simplicity. Communicate to help others understand the results. ??. ???????: Use the insight to solve the problem. The conclusion of the analysis should not remain to collect dust on the shelf. Note that the one who conducts the analysis isn’t always the one to make a decision. Recommendations based on the findings can be provided to enable ????????-???????????? ????????????????-????????????. Which step do you find the most challenging and the most interesting? Let me know in the comments. Stay tuned for Day 3 tomorrow, where we’ll explore the skills required to be a data analyst. #25DaysofData #DataAnalysis
