Chapter 1: Problem 5

Briefly explain the difference between a census and a sample survey. Why is conducting a sample survey preferable to conducting a census?

Short Answer

Expert verified
A census collects data from every individual in a population, while a sample survey collects data from a selected sample of a population. Conducting a sample survey is often preferable to conducting a census due to the reduced cost, quicker data collection and analysis, and the ability to provide accurate estimates with measurable error rates.

Step by step solution

01

Define Census

A census is a complete enumeration of a population or groups at a point in time with respect to well-defined characteristics, for example, population, production, etc. When a census is conducted, every unit in the population is surveyed.
02

Define Sample Survey

A sample survey, on the other hand, involves the selection and survey of only a sample of the entire population. In a sample survey, data is collected from a subset or a sample of the population, which is then used to draw conclusions or make generalizations about the population as a whole.
03

Compare Census and Sample Survey

While both census and sample survey are means of data collection, they differ mainly in coverage and scale. A census includes every unit of the population, while a sample survey includes only a subset of the population.
04

Advantages of Sample Survey

Conducting a sample survey can be preferable to conducting a census for a variety of reasons. Firstly, a sample survey is generally less costly than a census as it involves fewer resources. Secondly, because the sample size is smaller than the population size, it is often easier and quicker to collect and analyze the data. Thirdly, when properly designed and executed, sample surveys can provide accurate estimates of the population with measurable error rates.
