There are 25C7 different samples of seven from a pool of 25.

25C7 = 25!/(7!(25-7)!) = **480 700 different samples of
7**

### What is stratified random sampling in statistics?

Stratified Random Sampling: obtained by separating the
population into mutually exclusive (only belong to one set) sets,
or stratas, and then drawing simple random samples (a
sample selected in a way that every possible sample with the same
number of observation is equally likely to be chosen) from each
stratum.

### What is the definition of simple random sample?

There are two equivalent ways of defining a simple random sample
from a larger population.
One definition is that every member of the population has the
same probability of being included in the sample.
The second is that, if you generate all possible samples of the
given size from the population, then each such sample has the same
probability of being selected for use.

### What statistical tests can I use on data collected from quota samples?

The simple answer is you cannot use statistical tests on data
collected from quota samples.
Unless the sample was collected using a random sampling
technique you cannot have any confidence in the results being
representative of the population you are sampling. Quota samples
are non random.
However this does not stop researchers from using statistical
tests on quota samples, even if the results can be taken with a
pinch of salt!

### What is the difference between a simple random sample and a stratified random sample?

Sometimes a population consists of a number of subsets (strata)
such that members within any particular strata are alike while
difference between strata are more than simply random variations.
In such a case, the population can be split up into strata. Then a
stratified random sample consists of simple random samples, with
the same sampling proportion, taken within each stratum.

### What is the best definition for random sampling?

There are two equivalent definition.
Definition 1: A simple random sample is one for which each
element has the same probability of being included in the
sample.
Definition 2: A simple random sample is one where all sample of
that size have the same probability of being selected.
Although the words are similar, the first refers to the
selection of individuals from the population whereas the second
refers to the samples.

### 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 a random sample and a simple random sample?

This is a very vague area for new students in Statistics,
especially for non-math students.
Random Sample: Each member of the entire population has an equal
chance of being selected.
Simple Random Sample: You can select groups of size n from the
entire population, and every possible group has the same chance of
being selected.
Example: Consider a box with 100 marbles.
Random Sample: Reach in and select one marble. Each marble has the
same chance of being selected.
Simple Random Sample: Reach in and select marbles in groups of 6 (n
= 6). No matter how many times you do this, every possible group of
six marbles has the same chance of being selected. If you then try
selecting groups of 17 (n = 17) marbles, you will also find that
every possible group of 17 marbles has an equal chance of being
selected.
Random, but not Simple Random: For the Presidential Election, lets
say you select a random sample of all voting precincts in your
state, then interview *all the voters as they leave the polling
place. The sample is random because all precincts have an equal
chance of being selected. The sample is not simple random, because
those voters from precincts that were *not* selected have no chance
of being interviewed. This is also known as a Cluster Sample.
There is no such thing as a sample that is "Simple Random, but not
Random" because n can also equal a sample of size 1.

### Why do Social Scientists gather data from samples instead of populations?

It is simple statistics. It would be almost impossible to survey
an entire population, so they apply a simple random sample in which
each person in the population receives a numerical value (001 - 999
for example). Then they use a random number generator on a
calculator or use a random digit table to choose an appropriate
amount of people to be sampled. It is more cost effective and
easier to do it this way, yet still represents the population
fairly accurately.
