RESEARCH METHODOLOGY

Detailed explanation-1: -For both continuous and dichotomous variables, the confidence interval estimate (CI) is a range of likely values for the population parameter based on: the point estimate, e.g., the sample mean. the investigator’s desired level of confidence (most commonly 95%, but any level between 0-100% can be selected)

Detailed explanation-2: -A point estimate is a single number. Whereas, a confidence interval, naturally, is an interval. The two are closely related. In fact, the point estimate is located exactly in the middle of the confidence interval.
