🎣Statistical Inference

What do you learn in Statistical Inference

Statistical Inference digs into the art of drawing conclusions from data. You'll tackle probability theory, sampling distributions, and hypothesis testing. The course covers point estimation, interval estimation, and maximum likelihood methods. You'll also explore Bayesian inference and learn to make decisions based on statistical evidence.

Is Statistical Inference hard?

Statistical Inference can be pretty challenging, not gonna lie. The concepts can get pretty abstract and mathematical. But here's the thing - if you've got a solid foundation in probability and basic stats, you'll be fine. The trickiest part is often wrapping your head around the theoretical stuff, but once it clicks, it's not so bad.
