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.
