Chapter, 1.1 Sample, Statistic
Carlos Chacon


Sample statistic: is a limited number of observations selected from a population on a systematic or random basis, which (upon mathematical manipulation yield generalizations about the population. See also sample.

Definition: In my own words
The sample statistic refer to estimate the parameter distribution, such as the sample mean, sample variance, etc.

Examples:
The population for a study of infant health might be all children born in the UK in the 1980's. The sample might be all babies born on 7th May in any of the years.
