Statistics - How do I learn beyond first year statistics?

Hi team,

I studies statistics in my first year of Chemistry study. That was many years ago but I found it to be an amazing topic. I would like to learn more about statistics. Presumably what people would learn if they did a second or third year course in statistics but I don't know where to find study material.

What kind of textbook would teach me slightly more advanced statistics. I already know the basics of descriptive statistics as well as T tests, Z tests, Chi squad, regression, and ANOVA.

As an example, I would like to learn how to do a meta-analysis.

I got a book on Biostatistics and it seems to have a little bit of new content like geometric and harmonic means as well as discussions of case control and cohort studies.

I work full time and am not in a position to do formal study so this would just be for study in my own time.
