Confidence Intervals for Proportions | |
Summary |
there are many times when a proportion from a population is required. to estimate π, a proportion from a population, the proportion from a sample, p, can be used as a point estimate of π as with estimating the mean, a range of values with some level of probability or confidence that the population parameters will lie within this range is a better way to estimate the population proportion. this range of values is called a confidence interval for proportions. |
Key Skills |
