Why is it important to make sure you random sample is random?
It is important to make sure your random sample is random in order to make sure the results are accurate, and to prevent experimenter bias.
One way to ensure less sample bias?
Representative/random
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.

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 a random sample or one way to reduce when choosing people for an experiment?
