S3: Example of SRS - An Opinion Poll
Gallup Poll shows that 68% of Pakistanis would pick personality over beauty in a Life Partner.
The study was released by Gilani Research Foundation and carried out by Gallup Pakistan, the Pakistani affiliate of Gallup International. The recent survey was carried out among a sample of 1842 men and women in rural and urban areas of all four provinces of the country, during May 23 - May 30, 2016. Error margin is estimated to be approximately ± 2-3 per cent at 95% confidence level.
NOTE that only 1842 people were surveyed, but claims by Gallup are being made for the general picture in Pakistan. This is only possible due to Random Sampling.
