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.

Downloda thIS r ability check and must be able to One prerequisite for allOWing this other investigator to repeat an earlier Case study is the need to document the procedures follOwed in the earlier Case. 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.

Qualitative research refers to research method of collecting descriptive non-numerical data. The common instrument used to collect data are interview and observation, but Quantitative refers to research method of collecting numerical data. The common tools used to collect data are questionnaires and experiments. If a study aims to find out the answer to an inquiry through numerical evidence, then should make use of the Quantitative Research.
However some studies make use of both Quantitative and Qualitative Research, letting the two complement each other. If your study aims to find out, for example, what the dominant human behaviour is towards a reearch object or event and at the same time aims to examine why this is psf case, it is then ideal to make use of both methods. For instance it may be the textual, numerical or both textual and numerical.
Researcher select the qualitative research approach for research questions require textual data, researcher used quantitative research approach to respond to questions require the numerical data and the mixed method approach used when both the textual and numerical questions requires it. It builds its premises on the base of inductive reasoning and a researcher is highly involved with the subjects to collect, analyse and resezrch the results and give new insights about that phenomena.
