Can anyone please help me in understanding what confidence intervals are and how are they useful in statistics and machine learning?

  • $\begingroup$ We have 3,384 questions tagged "confidence-interval"., and there is an enormous amount of material on confidence intervals out there, starting with Wikipedia and continuing with any statistics textbook, including free ones. Please do a minimal amount of research before posting a question, and then ask about what specifically is still unclear to you. Thank you! $\endgroup$ – Stephan Kolassa Jun 17 '20 at 8:36
