WebOf course, we want the estimate to be "good" in some way. In this lesson, we'll learn two methods, namely the method of maximum likelihood and the method of moments, for deriving formulas for "good" point estimates for population parameters. We'll also learn one way of assessing whether a point estimate is "good." WebExample 1 Suppose that you want to find out the average weight of all players on the football team at Landers College. You are able to select ten players at random and weigh them. The mean weight of the sample of players is 198, so that number is your point estimate.

WebA point estimate is calculated from a sample. The point estimate depends on the type of data: Categorical data: the number of occurrences divided by the sample size. Numerical data: the mean (the average) of the sample. One example could be: The point estimate for the average height of people in Denmark is 180 cm. Estimates are always uncertain.
