4 Methods and materials<br />
This chapter describes the theoretical background, samples, research designs and<br />
procedures used as part of this thesis. It also describes the research questions and<br />
hypotheses as stated in the objectives of the thesis.<br />
4.1 Theoretical background of methods used<br />
In order to meet its research objectives, the thesis engages in both descriptive and<br />
causal research (Kotler, 2012). In terms of descriptive research, it aims to describe<br />
the effects of product placement and its possible causes. Survey research, which is<br />
elaborated on further on, is considered a proper method to engage in descriptive<br />
research. In terms of causal research, it aims to test hypothesis and cause-and-effect-relationships.<br />
Experimental research is considered a proper method to obtain<br />
causal information: this regards the selection of matched groups of subjects, subjecting<br />
them to various treatments, the control of factors which are not related, and<br />
verifying differences in responses of the groups (Kotler, 2012).<br />
In order to do so, the thesis utilizes several research methods to obtain primary<br />
data. Primary data concerns information which is gathered for a specific research<br />
goal, contrarily to secondary data which regards already existing data, which<br />
was gathered to meet a different goal (Kotler, 2012).<br />
The theoretical background of the methods used to obtain the primary data<br />
needed to comply with the thesis research objectives will be briefly described below.<br />
4.1.1 Questionnaires<br />
A questionnaire is a research instrument used in survey research. Survey research<br />
regards collecting data through asking people question regarding the knowledge,<br />
attitudes, preferences, and buying behavior, by asking them questions directly related<br />
to these aforementioned matters (Kotler, 2012). It is considered the most commonly<br />
used method to collect primary data, particularly suited to obtain information<br />
which is descriptive in nature. Advantages of this research can be found in its flexibility<br />
as it can be utilized to gather different kinds of information in varying situations:<br />
questionnaires can employ both open-end questions and close-end questions.<br />
Open-end questions allow the subject to answer to questions in their own words<br />
and thus there are no limitations imposed as to what the subject answers. Closedend<br />
questions on the other hand have a pre-defined set of answers defined among<br />
which the subject can choose to respond to the questions. The wording and ordering<br />
of questions is key in using questionnaires: these ought to be simple, unbiased and<br />
direct. Questionnaires can be conducted through various media, ranging from<br />
phone, to e-mail, to personal contact or event through the internet (Kotler, 2012).<br />
Survey research also comes with its disadvantages. These include an unwillingness<br />
to respond to interviewers they are not familiar with or due to the fact the responses<br />
queried might be too personal for the subject. The quality of the data might also be
