Research method based on multiple regression analysis

Research projects sometimes involve using multiple regression analysis; this can be carried out with Excel regression function, thus, it is handy. However, to conduct the analysis properly, you need to pay attention to a number of related issues in dissertation work, including (i) relevant literature review effort, (ii) the role of multiple regression analysis in the overall research design. Obviously, you need to study the relevant concepts in statistics learn the skill to design and analyze the findings. The following diagram depicts the main tasks involved:

Living systems theory - a brief note

The living systems theory is a systems methodology that adopts the organizational metaphor of living systems to study complex organizations and changes in complex situations. (Pratt, Gordon, and Plamping, 2005). There are articles on living systems theory published in systems journals from time to time.

On scientific management - a brief note

The main ideas of scientific managenment:

  1. Workers and their jobs as the basic organization building blocks
  2. Jobs are divided into simpler units as extensions of machine
  3. Much managerial/ supervisory effort to ensure workers' compliance with instructions and operations stability
  4. Supervisors absorb residual operational uncertainty and variabilities

Affiliated management concepts are (i) bureaucracy, (ii) machine metaphor in organization, (iii) Operational Research/ Management Science, (iv) industrial engineering (including work study), (v) business process re-engineering.

Some related concerns: (i) alienation, (ii) deskilling, (iii) mechanically paced motions, and (iv) demotivation. Also compare scientific management with human relation model and human resources model of management.

Conducting quantitative analysis with Excel - a brief note

Both Engineering Management and Business Management students might conduct quantitative analysis; I want to identify 2 main functions in Excel that are very useful for these quantitative exercises, as there is a misconception that doing  more sophisticated statistical analysis (e.g for final year projects) requires specialized statistical analysis software such as SPSS. Apparently, for professional practices in commercial enterprises, I still recommend using specialized statistical analysis softwares.

The first main function is Regression analysis; to use this function, you need to add in this function with "Analysis Tool Pak - VBA". Then, you will find this funcion  from "Data", then "Data Analysis"; then choose "Regression". You use this function to conduct multiple regression analysis.

The second function is Solver; you need add in this fucntion with "Solver add in". This function allows you to do linear  programming (solved with the simplex method). Again go to "Data", then "Data Analysis", then choose "Solver". See following exhibits:

Exhibit 1



Exhibit 2




In the case of linear programming, exhibit 3 and 4 below are provided for illustration (the figures are based on an example on simplex method from Lucey (2002):

Exhibit 3



Exhibit 4:



As to multiple regression analysis, the following exhibits are provided:

Exhibit 5

Exhibit 6:


Exhibit 7





Exhibit 8




Exhibit 9




Additional photos for illustration:

Photo 5


The main point is: Excel has a number of statistical and quantitative analysis functions that are in most cases sufficient to support students to conduct quantitative analysis in final year dissertation. The main challenge is to master the underlying quantitative techniques as the key steps involved in using Excel are quite simple and just take a few minutes (not to count the time spent on entering the raw data in Excel).

There are other quantitative/ statistical functions in Excel; I mainly use these two functions as major examples for illustration.
