What is relations between representative sample and population?
A representative sample is a randomly selected subset of the population.
What is the difference between the population and sample regression functions Is this a distinction without difference?
What is the difference between the population and sample regression functions? Is this a distinction without difference?
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
What is the difference between a population distribution and sampling distribution?
Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.
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 relations between representative sample and population?

What is the difference between representative and non representative government?
I believe the answer is in the names
What is the difference between a sample and sampling?

What is the difference between sample and example?
Definition of example is one (as an item or incident) that is representative of all of a group or type.Similarly, a definition of sample is1) a representative part or a single item from a larger whole or group especially when presented for inspection or shown as evidence of quality.Another definition of sample is2) a finite part of a statistical population whose properties are studied to gain information about the whole.The difference being that an example is typically one item and a sample is one or more items.
How To get valid results small samples are sufficient?
I will assume the sample is random. In general, the larger the sample, the smaller the percentage error will be (the difference between percentages in the sample, and the percentages in the universe from whence the sample is taken). The percentage error tends to go down as the square root of the size of the sample.
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
Why is obtaining a representative sample important?
Many statistical statements for a population which are based on a sample are not valid if the sample is not representative.
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
What is the difference between a population distribution and sampling distribution?
Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
Why is it important to have a representative sample when doing surveys?
Because without representative sample, your results will not be valid.
