What is CI (confidence interval)?
Confidence interval (also called CI): A range of values computed from sample data by a procedure that captures the true population value in a stated percentage of repeated studies. It expresses the precision of an estimate; it does not give the chance that this one interval contains the truth.
Confidence interval: an example
An average order value of Rs 850 with a 95% confidence interval of Rs 820 to Rs 880.
