A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.
to select a random sample you pick them at 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.
Random error and sample size have an inverse relationship...As sample size INCREASES random error DECREASES. There's a good explanation at the related link.
A defining characteristic of polyphony is that the independence and equality of simultaneous melodic lines.
The answer is Random Sample
random sample is a big sample and convenience sample is small sample
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.
In general when you take a sample of values of a random variable you will find that those values lie around some central value that is characteristic of the total population for the random variable. A measure of central tendancy (such as a sample mean, sample mode or sample median) is a statistic which is intended to estimate the central value of the population using the values in the sample in some way.
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

A random sample should be taken from an entire population.

No. A statistic is a number describing a characteristic of a sample.
