A <strong>Local</strong>-<strong>State</strong> <strong>Spatial</strong> <strong>Data</strong> <strong>Sharing</strong> <strong>Partnership</strong> Model to Facilitate SDI Development<br />

Case studies can be exploratory, explanatory or descriptive (Yin 1993). Exploratory case<br />

studies by their nature discover new theory. The hypotheses are developed progressively,<br />

and often after the completion of the data collection. However, they are sometimes<br />

criticised for lacking rigour and structure. The exploratory or descriptive approaches such<br />

as the example described by Williamson and Fourie (1998), provide an useful framework<br />

by which the cases can be described and classified. This thesis has adopted the descriptive<br />

and explanatory approach for analysing and describing the data sharing partnerships as it<br />

allows a more rigorous framework by which to classify the partnerships.<br />

4.3.3 Quantitative Methods<br />

Quantitative research uses numbers and statistical methods to explain and validate<br />

phenomena. Quantitative methods focus on “measurements and amounts (more or less,<br />

larger or smaller, often or seldom, similar or different) of the characteristics displayed by<br />

people and events that the researcher studies” (Thomas 2003, p. 1).<br />

The design approach and application of quantitative methods may differ significantly from<br />

a qualitative approach, but they may also converge. For example, both methods may<br />

utilise the use of theories as the basis for their design. For quantitative studies, a theory<br />

can help define the research questions, which then define the research variables or factors,<br />

and finally the instruments to measure these variables. This deductive approach becomes<br />

a framework for the entire study and an organizing model for the research questions and<br />

data collection procedures (Creswell 2003).<br />

Quantitative research may use a variety of strategies including the conduct of surveys or<br />

experiments. In the case of a survey or questionnaire, a number of target variables relating<br />

to the research questions are firstly defined and then data is collected via an appropriate<br />

method, analysed and presented. Experiments consist of treating objects in a defined way<br />

and then determining how the treatment is influenced under a variety of conditions<br />

(Thomas 2003). The strength of quantitative strategies lies in their ability to efficiently<br />

include a large number of participants through instruments such as surveys, and then the<br />

ability to analyse those variables comprehensively and quickly using computing methods.<br />

It also provides the potential to assist in identification of key factors, correlations and<br />

possible trends.<br />

4.3.4 A Mixed Method Approach – Best of Both Worlds<br />

The debate over the benefits of qualitative versus quantitative methods continues, with the<br />

proponents in each camp vigorously defending the benefits and rigour of each approach<br />
