Describine : methods to snow sample data
Inferential : Using daia to draw conclusions
Population : collection of an elements in a group
Parameter : Measurements to describe the expriation
sample : Sun collection of elements
Statistic : Measurements to describe a sample
ladden sampions : every element equally likely for select
based sample : Sample is not representative of Pop.
Control group : Studied group lot tested on

Placebo group : fake Treatment group to actual effect
experimental unit . The ihat

sampling Unit : The Part or characteristic of the
experimental ihai
