Term

Definition
A group of objects with common identifying characteristics; membership must be clearly defined 


Term

Definition

Term

Definition
Characteristic or property of a population 


Term
Random Sampling Variation 

Definition
The uncertainty surrounding estimates of parameters (standard error of the mean) 


Term

Definition
As sample size is increased, the accuracy of the statistic increases 


Term

Definition
The shape of the sampling distribution becomes normally distributed as sample size increases regardless of the shape of the population distribtuion 


Term

Definition
'peakedness' of the curve or fourth moment around the mean of a population distribution

Term

Definition
A frequency distribution of some random variable (i.e. X) for a population 


Term

Definition
A theoretical frequency distribution of some statistic (i.e. Xbar) for many samples of a given sample size from a population 


Term

Definition
A frequency distribution of some random variable (i.e. X) for a sample 


Term
