ASSIGNMENT
Course Code: MS-95
Course Title: Research Methodology for Management Decision

1. Discuss the significance and importance of the elements that make up the complete research problem.
Answer: Elements of complete research report :
It's also important for the writer / researcher to pay attention to the essential components of a research paper. While there are no templates for writing it, there are standard components of which one may do well to have a good understanding.
Title: The title page, with the alignment of the actual title of the paper typically centered.
Table of contents (with page numbers for each section)



2. How would you use a Likert scale to ascertain the image of a leading computer brand among some consumers?
Answer: A “Likert scale” is actually the sum of responses to several Likert items. These items are usually displayed with a visual aid, such as a series of radio buttons or a horizontal bar representing a simple scale.
In a “good” Likert scale, the scale is balanced on both sides of a neutral option, creating a less biased measurement. The actual scale labels, as well as the numeric scale, may vary.
A “Likert Item” is a statement that the respondent is asked to evaluate. In the example below, this item, “The checkout process was easy” is a Likert


3. A group of 11 students selected at random secured the grade points: 1.5, 2.2, 0.9, 1.3, 2.0, 1.6, 1.8, 1.5, 2.0, 1.2 and 1.7 (out of 3). Use the sign test to test the hypothesis that intelligence is a random function (with a median of 1.8) of 5% level of significance.
Answer: Solution: The Null Hypothesis
The intelligence is a random function i.e.
The intelligence is not a random function i.e.
Given, Median = 1.8


4. Write a short note on Regression Analysis, Discriminant Analysis and Factor Analysis.
Answer: Regression analysis
Regression analysis is one of the most extensively utilized method between the analytical models of association employed in business research. Regression analysis tries to analyze the connection between a dependent variable and a group of independent variables (one or more). One example is, in demand analysis, demand is versely linked to price for normal commodities. We can write D = A – BP, where D is, the demand which is the dependent variable, P is the unit price of the commodity, an independent variable. It is an example of a simple linear


b. Discriminant Analysis
Answer: More easily interpreted than an eigenvalue, though, is a direct expression of the proportion of between-group separation that is provided by each discriminant function.  This proportion is computed by dividing the eigenvalue for a given discriminant function by the sum of the eigenvalues for all of the discriminant functions.
In SPSS the loadings are called the Cannonical


c. Factor Analysis
Answer: Factor analysis attempts to identify underlying variables, or factors, that explain the pattern of correlations within a set of observed variables. Factor analysis is often used in data reduction to identify a small number of factors that explain most of the variance that is observed in a much larger number of manifest variables. Factor analysis can also be used to generate hypotheses regarding causal mechanisms or to screen variables for subsequent analysis (for example, to identify collinearity prior to performing a linear regression analysis).


5. Write a brief note on the importance of elements of communications dimensions namely purpose, Audience, Media, Message, Time, Place and cost.
Answer: Communication is a significant part of a manager’s job. In today’s team-oriented workplace, the development of good interpersonal communication skills is an important key to success. To build the competence and commitment of employees, a manager has to communicate effectively. Through effective communication, a manager can mobilize the employees behind an organization’s vision and inspire a conscious and concerted team effort to attain the vision. The pay-off of effective communication is:
• A more professional image
