1. Analysis and decision making is an important discipline

which integrates the tools of quantitative and qualitative

analysis with decision making process. An emphasis is

placed on real-life examples to develop the skills

necessary to apply the relevant tools in both

quantitative and qualitative analyses and decision

sciences in deriving optimum business and

organizational decision makings.

2. Both quali and quanti tools will be covered as listed in

the course contents.

3. Among the three major topics covered in this data

analysis course are:

i. “feel for the data”, ii. “goodness of data”, and

iii. “analysis of data”.

4. The integration of statistical software decrease the

need for manual computation and students can

devote more time on the interpretation of results.

Students are however encouraged to master manual

calculations in order to appreciate the statistical

concepts.

5. Students are expected to be able to recognize the

various statistical approaches to adopt when presented

with data. Therefore they are expected to be able to

recognize the business problems, formulate hypothesis

and determine test methods and statistics involved and

provide sound business interpretations in order to be

able to impart advice based on the analysed data.

• To familiarize students with concepts involved in various

data analysis technique and its application in research.

• To guide students to compute, perform data analysis and

provide inferences for descriptive measures of data.

• To encourage students to participate in decision making

by applying various qualitative and quantitative

techniques.

Page 6: Data Analysis

• After completing this course, the students should be able:

• to evaluate the relevancy and suitability of various data analysis technique and its application in research.(LO1, C6)

• to construct various data analysis techniques by using qualitative and quantitative tools (software). (LO2, P4)

• to produce a preliminary data analysis results based on the proposed research area (LO7- LL3, P6).

1. Systematically applying statistical and/or logical techniques

to describe and illustrate, condense and recap, and

evaluate data.

2. “provide a way of drawing inductive inferences from data

and distinguishing the signal From the noise Present in the

data”. (Shamoo and Resnik, 2003).

3. In qualitative research analysis becomes an ongoing

iterative process where data is continuously collected and

analyzed almost simultaneously. Researchers generally

analyze for patterns in observations (Savenye, Robinson,

2004).

4. The form of the analysis is determined by the specific

qualitative approach taken (various methodology).

5. Data integrity is ensured through the accurate and

appropriate analysis of research findings. Improper

statistical analyses distort scientific findings, mislead casual

readers (Shepard, 2002).

6. Integrity issues are just as relevant to analysis of non-

statistical data as well.
