STATS 7 Lecture Notes - Lecture 13: Confidence Interval, Interval Estimation, Statistical Parameter
Document Summary
A single number used to estimate a population parameter. Point estimate = sample statistic = sample estimate. An interval of values used to estimate a population parameter. Sample estimate +/- (multiplier x standard error) margin of error . An interval of values computed from sample data that is likely to include the unknown value of a population parameter. The entire collection of units about which we would like information or the entire collection of measurements we would have if we could measure the whole population. A fixed summary number associated with a population, and in the context of confidence intervals is unknown and we want to estimate if. E. g . p is the proportion of the population with a particular characteristic. The collection of units we will actually measure or the collection of measurements we will actually obtain. The number of units or measurements in the sample, denoted by n.
