Does a random largely selected sample always give a better estimate of the population than a randomly selected sample?
A larger random sample will always give a better estimate of a population parameter than a smaller random sample.
What is the definition for the sample of a population for which each has an equal chance of being selected?
Random Sample
What is a survey of a representative sample of the population called?
Random selection.
Does a Quota Sample represent the whole population?
yes because the quota sample include the random sample and when we have over estimation we will use the quota 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.
Which conditions may be met for a scientifically valid sample?
at random to represent the population
A random sample should be taken from?
A random sample should be taken from an entire population.
Does a random largely selected sample always give a better estimate of the population than a randomly selected sample?
A larger random sample will always give a better estimate of a population parameter than a smaller random sample.
The whole population to be measured in a scientific poll is the?
random sample or probability sample
How can you determine whether a sample is representative of a population?
Take a simple random sample.
What is a biased sample?
A biased sample is a sample that is not random. A biased sample will skew the research because the sample does not represent the population.

When can statistics be used to gain information about a population from a sample?
When the sample - whether it is random or systematic - is somehow representative of the population.
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.

Random Sample
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.

Random selection.
