STA630 Research Methods Assignment 1 Solution Fall 2012


“Superior  Denim”  is  a  denim  producer  and  a  market  leader  which  not  only  exports  to  the  leading brands internationally but  also has  its operational outlets nationwide. The organization, with a  total of  7000 employees, has a strong  labor union which is now  involved in some violent activities during various recent strikes. The strike which started  last week and  is  still  continued, has  resulted  in  three  injured one of which  is  critical. Management observed more aggressive attitude and increased violence with every new strike. The CEO has decided to look into the  issue  and  has  invited  an  organizational  psychiatrist, Mr. Ashar, who  conducts  research on  different areas  of psychology.

It is brought to Ashar’s notice that labor was recently hired that belonged to similar demographics, sharing a
similar cultural background. Few of them are identified to have a criminal background as well, and they are holding
prominent positions in the labor union. The labor is also found not to be satisfied with the job conditions and is
not provided with proper health and safety measures that are required for the job they are performing.

Mr.  Ashar  is  asked  to  analyze  the  situation. He  is  trying  to  find  out  the  reasons  of  recent  increased  cases  of
violence  among  employees. After  initial  analysis,  Mr.  Ashar  found  that  mindset  of  employees  and  cultural
background played a significant role in recent violence.


Keeping in view the scenario given above, answer the following questions with justification.

1.  Identify the variables.  3
2.  Identify dependent and independent variables.  3
3.  What type of relationship exists among the variables?  4
4.  Develop appropriate null and alternative hypothesis for given case.  3+3
5.  Justify how it is a testable hypothesis.  4 IMPORTANT:

24 hours extra / grace period after the due date is usually available to overcome uploading difficulties. This extra
time should only be used to meet the emergencies and above mentioned due dates should always be treated as
final to avoid any inconvenience.

Step 1:
Read the scenario generally in order to understand it.
Step 2:
Read the questions.
Step 3:
Relate the concepts asked in the questions with the recommended books.

Questions Solution Marks Marks awarded
Identify the variables.  

Employee, Injuries, Job Satisfaction, demographics



Identify dependent and independent variables. Dependent Variables:

Employees, Injuries, Job Satisfaction.

Independent Variables:

Organization, Labor’s criminal background, labor positions in labor union.





What type of relationship exists among the variables?            

Causal relationship.


Develop appropriate null and alternative hypothesis for given case. Null Hypothesis:

The Union strikes are not caused by lack of job satisfaction, employee’s criminal background and job conditions.

Alternative Hypothesis:

The union strikes are caused by the employee’s lack of job satisfaction, criminal background and job conditions.








Justify how it is a testable hypothesis. In first step we will find the association between union strikes and job satisfaction, criminal background of employees and job conditions. Then we will find the severity or the strength of this association. We test hypothesis indirectly by testing the null hypothesis. If we have any credibility in our hypothesis it will reject null hypothesis. Rejection of null hypothesis will lead to accept the alternative hypothesis.
