<p>Jan 26, 2011 02:06 PM
 
CLT =  the mean of a large number of indep random variables is approx normally distributed.
(the variables must be identic. distributed (eg coin tosses))
 
the theorem provides an explanation for the prevalence of the normal prob distribution in nature.
 
CLT justifies the use of the normal distrib in large-sample statistics.
