This week within chapter 7 the author Judith A. Boss discusses
the topic of sampling. Sampling is the process in selecting only some members
of a class or group and then making a generalization about the whole
population. For example, they will take
a small sample group from a large population and give them a poll and make a
generalization from those results. There are a few different types of samples.
The first one is a representative sample, which is a sample that is similar in
relevant respects to the larger population.
To get the results needed in a Representative sample you need to use the
method of random sampling which is every member of the population has an equal
chance of becoming a member of the sample. Lastly there is a sample that is
known as self-selected sample, which is only the people interested in the poll
actually take the time to participate in it.
