Depends on the context for trying to catch up; both where you're at in life and what you're wanting to get out of it.
If you want to connect, feel free to reach out to the email in my profile. I may not be the best resource for best places to go next depending on what you're after, but may be able to help out.
A few general points though:
- Every field has it's own flavor of statistics. Supply chain, marketing, industrial engineering, business operations, finance, etc. Most practitioners will bastardize a technique or methodology common in their field before reaching out to another one for something more appropriate. Keep this in mind when looking at things, as you can find a lot of cases where the general premise for a technique is no longer valid, but practitioners are still going on momentum. You can also find some really neat nuggets/advancements that can be generalized and applied to another field. Although this can be difficult to suss out, as every industry tends to develop their own vernacular to refer to a particular set of base statistical techniques.
- Focus less on the math and more on the applicability of a particular technique or methodology to a situation. Generally speaking, statistical techniques are nothing more than sophisticated heuristics. Their validity, applicability, and actionability are entirely dependent on the situation they're applied in and the particular heuristics (statistical techniques) chosen. Understanding the techniques that are out there, what their applications are, and what their limitations are is far more useful than focusing purely on the math. The math can always be looked up once you know what to look up.
- Design of experiments[1] is a critical and often overlooked concept. It's rarely done in practice, and even when it is it's rarely more than a superficial attempt. But is a hugely important concept to understand how to approach a problem space.
- The output of a statistical analysis ranges from "checks the box of measuring something but so disconnected from observed reality that it'll otherwise be ignored" to "interesting but not robust enough to make decision on" to "directionally accurate" to "willing to make decisions based on confidence intervals". Understanding where your analysis stands on that scale, and where it needs to stand to meet your needs, is critical. Align your efforts with your needs, and set expectations accordingly.
