studying or examining a segment of the population to represent the whole so that generalization can made
Samplig
units which are chosen in selecting the sample
Sampling unit
list of all sampling units from which sample is drawn
Sampling Frame

Target Population
information collected from the sample
Statistics
information collected from the population
Parameter
study sample data to make inferences or generalizations about the population
Uses parametric & non-parametric tests

Involve summarizing & organizing the data so it can be easily understood
used to determine the characteristics of the data on hand
uses graphical & analytical methods
