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.
The chief aim is to find a representative sample; that is, a sample which reflects the properties of the population, as a whole.
the participants are representative of the population they are interested in studying
a stratified random sample
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.
There is no sampling method that will select the exact population.

The popo ulation in the people/items you have collected data from. if you are sampling, the its the population of which you select your sample from
A sample of a population that has been selected using a pattern is when a researcher selects every 10th person from a list or sampling frame. For example, if a researcher wants to study the attitudes of employees in a large company, they may select every 10th employee from the company directory. This method ensures a systematic pattern in selecting the sample.
Sure it can. But in the survey business, the trick is to select your sample carefully so that they'll be equal, i.e. a sample that is accurately representative of the population.
To conduct a survey with a sample size of 3/8, you would need to select 3 out of every 8 individuals in your population to participate in the survey. This can be done by using a random selection method or by dividing your population into groups of 8 and selecting 3 individuals from each group.

A sample frame is a list of population units/elements commonly referred to as sample members from which to select units/elements to be sampled. Regards Siphokazo Mondliwa
To conduct a study using the 5/8 method, researchers divide a sample into five equal groups and randomly select 8 participants from each group. This method helps ensure a representative sample for research purposes.
a stratified random sample
to select a random sample you pick them at random
the participants are representative of the population they are interested in studying
