what is needed for simple random sample?
A reason for requiring a sample.
How can you determine whether a sample is representative of a population?
Take a 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.

When dividing a population into subgroups so that a random sample from each subgroup can be collected?
simple random sampling
A sample selected in such a way that each members of the population has an equal probability of being chosen?
That is known as a simple random sample, or SRS.
Which conditions may be met for a scientifically valid sample?
at random to represent the population
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.

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!
When dividing a population into subgroups so that a random sample from each subgroup can be collected?
simple random sampling
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 sample selected in such a way that each member of the population has an equal probability of being included?
It is a simple random sample.
What is the preferred method to select a sample population?
simple random sampling method
