Explain how you could create a distribution of means by taking a large number of samples of four individuals each?

As the sample size increases, and the number of samples taken increases, the distribution of the means will tend to a normal distribution. This is the Central Limit Theorem (CLT). Try out the applet and you will have a better understanding of the CLT.

How do channels of distribution create value?
So, a channel of distribution involves an arrangement of exchange relationships that create value for buyers and sellers through the acquisition (procurement), consumption (usage), or elimination (disposal) of goods and services.
How are sampling distributions generated using the empirical sampling approach?
Depending on the number of samples involved, you either simulate all possible samples or you simulate taking a large number of samples. The distribution of he sampling statistic can be calculated from these. Here's a Python script that demonstrates how to do this in a simple form. Suppose you want to experiment with the sampling distribution of the sample mean for samples of size 5 drawn from a normal population with mean 0 and standard deviation 1. There are, of course, mathematical results that establish the exact sample distribution of this statistic. Let's pretend we don't know that. Usually it's necessary to generate many, many samples to establish a sampling distribution. For the purposes of this exercise this code generates only 20. from scipy.stats import norm N = norm ( 0., 1. ) ## create source of N(0,1) deviates x_bars = [ ] ## create place to hold sample x_bar values for s in range ( 20 ) : ## run experiment 20 times x_bars . append ( sum ( N . rvs ( 5 ) ) / 5. ) ## make & store sample x_bar values x_bars . sort ( ) ## form the so-called order statistics for the sample for i, x_bar in enumerate ( x_bars ) : ## print empirical distribution function print '%.2f %.2f' % ( ( i + 1 ) / 20., x_bar, ) When I ran this code I got the following: 0.05 -1.65 0.10 -0.28 0.15 -0.25 0.20 -0.10 0.25 -0.09 0.30 -0.08 0.35 0.01 0.40 0.05 0.45 0.10 0.50 0.12 0.55 0.13 0.60 0.19 0.65 0.41 0.70 0.46 0.75 0.50 0.80 0.55 0.85 0.67 0.90 0.79 0.95 0.94 1.00 1.05 If you plot these using the column on the left as the x-axis you will get the so-called empirical distribution function. The sample values can also be used in a variety of ways to obtain estimates of the sampling probability density. Please see the link for the basics.
How does distribution of scores affect selection of statistical procedures?
There are two broad cases: either you know the distribution or you don't. Distribution known: Procedures are known for many, many situations. In some cases, it's possible to transform given data to fit available procedures. In other situations, it might be necessary to create new procedures. Distribution unknown: Often a procedure that was developed for known distributions has been shown to work for distributions that are only similar to the known distributions. Recourse may alternatively be had to the so-called nonparametric statistics, that make minimal assumptions about distributions.
