Properties & assumptions formulae correction for continuity confidence interval for difference between two proportions an in medical research the difference between proportions is commonly referred to as the risk difference.
We will need to know the mean, the standard deviation, and the particular distribution that we are working the result is the following formula for a confidence interval for a population proportion Calculating a confidence interval for the difference of proportions. It is difficult to imagine how our life would be without two ratios are said to be in proportional if they are equivalent. Formulas for ratio and proportion questions:
