What is the best description of a stratified random sample?
the same chance of being selected for each personequal representation for all groups
When would random sampling not be the best approach to sample selection?
When would random sampling not be the best approach to sample selection
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
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 the difference between random and stratified sample in the survey method?
The main difference is that the way of selecting a sample Random sample purely on randomly selected sample,in random sample every objective has a an equal chance to get into sample but it may follow heterogeneous,to over come this problem we can use stratified Random Sample Here the difference is that random sample may follow heterogeneity and Stratified follows homogeneity

What is random distribution in biology?
A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.
How do you select sample size in market research?
to select a random sample you pick them at random
A random sample should be taken from?
A random sample should be taken from an entire population.
Is the best description of a stratified random sample?
Stratified random sampling is a form of probability sampling that provides a methodology for dividing a population into smaller subgroups as a means of ensuring greater accuracy of your high-level survey results. The smaller subgroups are called strata. Stratified random sampling is also called proportional or quota random sampling.
Which conditions may be met for a scientifically valid sample?
at random to represent the population
