Hello there, what are you expecting from such comparrison ? Can you explain and describe in more detail what do you mean by "link both data"?

I agree that we need to know more, for example, what are "datasets of different datatypes?"

Nonye Celestina Akagbobi What parameters are different?

If parameters are not same how can you compare them? On what basis you want to compare?

You use the terms "compare" and "correlate". Those are two very different activities (one is useful for answering questions like "which is bigger", while the other is useful for answering questions like "does variable A increase as variable B does?"). Without using either term (or any statistical term at all, hopefully), what is it that you're trying to find out

It is difficult to understand your question, but assuming that what you want is to compare different data, you should first normalize them and then you can calculate the statistical metrics for comparison.
