As very clear from the name quantitative survey is all about objective measurement and statistical values. A definite population is surveyed upon with a set of questions. This definite set of population is scientifically calculated sample of people and representative of the population. The survey enables to determine the frequency and percentage of their responses.

Quantitative research is actually the numbers game. The sample size is designed by statisticians using formulas to determine how large a sample size is required from a given population in order to accomplish findings with an acceptable degree of accuracy. Generally, researchers seek sample sizes which will yield findings with at least a 95% confidence level (which means that if you repeated the survey 100 times, 95 times out of a hundred, you would get the same response) and a plus/minus 5 percentage points margin of error. Many survey samples are designed to produce smaller margins of error.
