NOTES: Sampling Distributions n = sample size x = sample mean = average of a quantitative variable describing a SAMPLE µ = population mean = average of a quantitative variable describing the POPULATION p^ = proportion of the SAMPLE with trait n traithave which SAMPLE in the sindividual ofnumber = p = proportion of the POPULATION with trait sizepopulation traithave which POPULATION in the sindividual ofnumber = Statistic: a number which describes a sample. Examples: x , xS , p^ , n Parameter: a number which describes a population. Examples: µ , ? , p Sampling Distribution: The sampling distribution of a statistic is the distribution of values taken by the statistic in all possible samples of the same size from the same population. Unbiased Estimator: A statistic used to estimate a parameter is unbiased if the mean of its sampling distribution is equal to the true value of the parameter being estimated. Example: ( ) ...
