Definition of confidence intervals
Check what you remember
Read the wording for your board, then hide it and explain confidence intervals in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A range is put around a sample figure, so a survey result quoted with an interval at the usual level says the real figure very probably lies within that range.
