Research Designs/Methods There are three commonly used approaches of doing research for phenomena of interest or under studied are Qualitative, Quantitative and Mixed methods which depends . Quantitative and qualitative research methods differ primarily in: • their analytical objectives • the types of questions they pose • the types of data collection instruments they use • the forms of data they produce • the degree of flexibility built into study design Table 1, page 3, briefly outlines these major differences. Quasi-experimental research designs, like experimental designs, test causal hypotheses. A quasi-experimental design by definition lacks random assignment. Quasi-experimental designs identify a comparison group that is as similar as possible to the treatment group in terms of baseline (pre-intervention) characteristics.

The concept of ambient intelligence has been with us for some time now. Originally known as ubiquitous computing, its aim was to disperse the inherent "intelligence" availa- ble in the PC throughout the user environment.

    The recent proliferation of the Internet, coupled download the advent of wireless technologies like Bluetooth, has brought the pos- sibility of truly distributed intelligence closer than ever. But the whole ambient intelligence concept raises many questions.

    One of the most fundamental is just how "intelligent" people want their environment to be. After all, there is a fine line between what is perceived as helpful and useful, and what is considered intrusive, overbearing and overly complex.

Four tests may be considered relevant in judging the quality of a research design.

    In designing and doing case studies, various tactics are designs designs available to deal with these tests, though not all of the tactics occur at the formal stage of designing a case study. Some of the tactics occur during the data collection, data analysis, or compositional phases of downpoad research and are therefore described in greater detail in subsequent chapters of this book.

    Four types of designs will be discussed, based on a 2 x 2 matrix see Figure 2. The matrix assumes that single- and multiple-case studies reflect different design situations and that, within these two types, there also can be a unitary or multiple units of embedded analysis. Thus, for the case study strategy, the four types of designs are a TYPE 2 TYPE 4 multiple units single-case holistic designs, b single-case embedded designs, c multi- ple-case holistic designs, and d eesearch embedded designs.

    The of analysis rationale for these design types of designs is as follows. This means the need for a decision, prior to any data collection, on whether a single-case study research multiple cases are going to be used to research the research questions.
