In the present day, different surveys can be carried out by
the government and by the private enterprises. The government surveys consist
of census, but the private companies carry surveys to get customers’ opinions
on any product.
The best example is toy companies who prepare a questionnaire
on a paper to get desired results. The sampled people are from schools and also
the young ones. Then the conclusion came that those toys are mostly liked by
the young ones. On the other hand, the government carries out a census every 10
years by getting detail from every home.
