It is called convenience sampling.
The answer depends on the underlying variance (standard deviation) in the population, the size of the sample and the procedure used to select the sample.
simple random sampling method
The chief aim is to find a representative sample; that is, a sample which reflects the properties of the population, as a whole.
The sampling universe is the totatility of items/events from which you can select or sample for statistical analysis and description.
simple random sample is to select the sample in random method but systematic random sample is to select the sample in particular sequence (ie 1st 11th 21st 31st etc.)• Simple random sample requires that each individual is separately selected but systematic random sample does not selected separately.• In simple random sampling, for each k, each sample of size k has equal probability of being selected as a sample but it is not so in systematic random sampling.
to select a random sample you pick them at random
The main difference between the quota and stratified sampling is that in the stratified sampling the researcher can not select the individuals to be included in the sample (he doesn't have control over who will be in the simple), but in the quota sampling the researcher has control over who will be in the sample (he can contact certain people and include them in the sample).
It depends on the what the sample is for, but at least get both girls and boys in the sample.
