

A primary objective in statistics is to derive conclusions about a larger population
based on information from a sample.
The role of statistical evidence becomes paramount, especially when used to infer
characteristics of broader populations.
6. Understanding Populations and Census



In statistical studies, a 'population' refers to the complete set of individuals or
entities about which conclusions are to be drawn.
'Census' denotes a comprehensive study involving all individuals within a given
population.
Populations in studies can vary: from people and animals to even more abstract
entities.
7. Challenges in Comprehensive Data Collection


Due to the vast nature of many populations of interest, collecting data from every
individual often becomes impractical.
The inherent challenges associated with exhaustive data collection underscore
the importance of effective sampling techniques.
