- We can estimate population parameters using either a point estimate or intervals. Unlike point estimates, interval estimation provides a measure of how close the estimate is to the true value of the parameters, known as the margin of error. By using estimation with one sample, this sample could include the true parameter or not; however, by using multiple samples, this probability will vary according to the chosen size of the interval. The first section of the lecture deals with the central limit theorem and calculation of the probabilities. The second section deals with the estimation of the unknown mean when the population's standard deviation is known.
