Solution:

A support group has 14 patients that attend each week. Suppose 3 patients are selected at random to participate in a study. How many different samples of this size can be selected from this population of 14 patients using experimental sampling and theoretical sampling?

a) Experimental sampling:

Numbr of samples possibe=NCn

N=14,n=3

Number of samples possible=14C3=14!/3!12!

=(14 * 13 * 12) / (3 * 2 * 1)

= 364

b)Theoretical sampling:

Number of possible sample=Nn= = 2744
