There are two equivalent ways of defining a simple random sample from a larger population.
One definition is that every member of the population has the same probability of being included in the sample.
The second is that, if you generate all possible samples of the given size from the population, then each such sample has the same probability of being selected for use.

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.
At a large University a simple random sample of 5 female professors is selected and a simple random sample of 10 male professors is selected The two samples are combined to give an overall sample of?

What is the definition of a sample space?
the range of values of a random variable.

Simple Random Sample
What You decide you want your sample to be representative of the population. Which sampling process would provide the most representative sample?
A simple random sample.
What is the best definition for random sampling?
There are two equivalent definition. Definition 1: A simple random sample is one for which each element has the same probability of being included in the sample. Definition 2: A simple random sample is one where all sample of that size have the same probability of being selected. Although the words are similar, the first refers to the selection of individuals from the population whereas the second refers to the samples.

What is the definition for the sample of a population for which each has an equal chance of being selected?
Random Sample
How can you determine whether a sample is representative of a population?
Take a simple random sample.
What is the definition of a sample space?
the range of values of a random variable.
What does SRS mean in statistics?
Simple Random Sample
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.

How do sampling methods effect the rigor of a study?
A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.
A way to collect survey data?
A simple random sample is good!
