Kaggle Datasets are often too perfect for real-world scenarios. I'm about to share a method for real-life data analysis. You see … … most of the time, a data analyst cleans and transforms data. So … let’s practice that. How? Well … you can use ChatGPT. Just write this prompt: Create a downloadable CSV dataset of 10,000 rows of financial credit card transactions with 10 columns of customer data so I can perform some data analysis to segment customers. Now… Download the dataset and start your analysis. You'll see that, most of the time… … numbers don’t match. There are no patterns. Data is incorrect and doesn’t make sense. And that’s good. Now you know what a data analyst deals with. Your job is to make sense of that dataset. To create a story that justifies the numbers. This is how you can mimic real-life work using A.I.
