Random sampling simply means the sample you chose from a population for a particular statistics must be random and not biased. One way is to have all names of the population to be randomly drawn by a computer system or a manual system (eg. drawing names from a fish bowl). Obtaining statistics information from a supermarket or from a particular group of social group is not random sampling as it is believe people of the same group has the same opinion.
Eg. If you want to do a survey on how often people shop in Walmart, obtaining sample from Walmart shoppers is NOT random sampling because you are only doing survery on those who are already shopping in Walmart. Instead do random survery in a particular work environment unrelated to Walmart or door by door interview as this will allow access to a variety of people including those who never shop in Walmart (a data you cannot obtain from Walmart shoppers)

When you draw a sample from a normal distribution what can you conclude about the sample distribution?
The answer depends on how the sample is selected. If it is a simple random sample, of size n, then it is distributed approximately normally with the same mean as the population mean.The answer depends on how the sample is selected.

What is the difference between simple random sampling and systematic random sampling?
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.
What is the difference between random and stratified sample in the survey method?
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
