Social networks (Facebook, Orkut, MySpace, Bebo, LinkedIn) are not only changing the way that many people use the Internet, but they are also presenting marketing practitioners with new challenges when trying to reach and acquire customers online. At the same time, these social networks have their own challenges in trying to acquire and retain customers when many of the traditional principles of consumer behaviour no longer apply. As social networks become more popular, a marketing dissertation in this area would be up to date and in line with current trends.
Even if you used a quantitative research design, but failed to employ a probability sampling technique, there are still many perfectly justifiable reasons why you could have made such a choice. For example, it may have been impossible (or near on impossible) to get a list of the population you were studying (., a list of all the 20,000 students at the single university you were interested in). Since probability sampling is only possible when we have such a list, the lack of such a list or inability to attain such a list is a perfectly justifiable reason for not using a probability sampling technique; even if such a technique is the ideal.
The recent proliferation of online Universities offering PhD degrees (such as NCU, Capella, UoP, etc) has led to the situation of students often being ill-prepared to complete the dissertation process without seeking outside assistance from a dissertation consultant who is familiar with the specific processes followed at these schools. Since expanding our client base to include PhD candidates, we have helped these students save tens of thousands of dollars in tuition, while graduating months earlier than their peers. Offering dissertation help to PhD candidates is now one of the top priorities of our firm.
