In order to do a systemic random sample, the items or individuals in the population are arranged in a certain way (for example, alphabetically). A random starting point is selected and then every __th (for example: 10th or 15th) individual is selected for the sample.
In math, a biased example could be when, someone asks only males to answer "do you like this product." its when the people chosen to answer the survey/sample is not random
With random sampling, you are hoping to get a representative sample of a whole, however statistically you could get a sample that is very different from the whole it was selected from. The larger the sample proportion of the whole, the better your sample will be. For example, a sample of 10 out of 100 is not as good as 20 out of 100. The bigger the sample the closer to the actual whole average you will get.
A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.
to select a random sample you pick them at random

The answer is Random Sample
random sample is a big sample and convenience sample is small sample
Biased- (Not random) Unbiased-(Random) Example: (ubbiased) Woman takes random people to take a survey.
In math, a biased example could be when, someone asks only males to answer "do you like this product." its when the people chosen to answer the survey/sample is not random
stratified random sampling is a sample(strata) that a same and hemogenieous in group and that a different and heterogenious in group
With random sampling, you are hoping to get a representative sample of a whole, however statistically you could get a sample that is very different from the whole it was selected from. The larger the sample proportion of the whole, the better your sample will be. For example, a sample of 10 out of 100 is not as good as 20 out of 100. The bigger the sample the closer to the actual whole average you will get.
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.
The main difference is that the way of selecting a sample Random sample purely on randomly selected sample,in random sample every objective has a an equal chance to get into sample but it may follow heterogeneous,to over come this problem we can use stratified Random Sample Here the difference is that random sample may follow heterogeneity and Stratified follows homogeneity
A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.
A random sample should be taken from an entire population.
