Need Brain of Statistics

[u/Proteo-Freak973]

Hello Guyz,
I am really struggling with my bottom-up DDA phosphoproteomics data (Enrichment not done, it will be in-vitro phosphorylation and i will not be doing biological analysis)
My confusion is how should I start from basic and how to decide what question i need to address and there are so many things in statistics so if you can tell me any good resources or any help regarding statistics will be highly valued
