In point estimation,
- a. data from the sample is used to estimate the population parameter
In statistics, point estimation involves the use of sample data to calculate a single value (known as a point estimate since it identifies a point in some parameter space) which is to serve as a "best guess" or "best estimate" of an unknown population parameter (for example, the population mean).

True or false A The value of a statistic is often used to estimate the value of a parameter. B. The value of a statistic is computed using the data in a given sample. C. The value of a parameter is usually unknown, because we cannot obtain data for the entire population. D. The value of a statistic is usually unknown, because we cannot obtain data for the entire population. E. A statistic is a number that describes a population....

Estimators are used in two different ways: point estimation and confidence estimation.
(36) Estimators are used in two different ways: point estimation and confidence estimation. (1) True. (2) False. (37) Which of the statements about large-sample estimation is correct? (1) An estimator should be unbiased and the spread (as measured by the mean) should be as small as possible. (2) The distance between an estimate and the true value of the statistic is called the error of estimation. (3) The 95% Margin of error is: 1.96 x Standard error of the estimator. (4) A good confidence interval is as...
