Introduction to Research Methods Task 2 Question a) A Bar chart showing mean ratings for job satisfaction, organizational commitment and work stress against respondents’ education b) summary table showing the mean ratings for job satisfaction, organizational commitment and work stress by respondent education     job satisfaction Organisational commitment Work Stress Education           Primary 18.63 21.80 1.38 Secondary 18.07 21.85 1.34 A Level 21.06 20.50 0.88 Diploma 18.67 22.07 1.

6 Bachelor 19.71 22.92 1 Master or above 22.75 21.50 1.5 The statistics obtained show that respondents with the highest job satisfaction were Master’s degree holders or above. Organisation commitment was relatively the same for all education levels though respondents with bachelors had the highest. Responds with masters or above had the highest work stress while A-level holders had the lowest work stress. Question 2 a) A Bar chart showing mean ratings of job satisfaction, organizational commitment and work stress against respondents’ positions in the company b) summary table showing the mean ratings for job satisfaction, organizational commitment and work stress by respondent position in the company     Job satisfaction Organisational commitment Work Stress Respondent position   Worker 18.13 21.54 1.

22 Supervisor 19.33 22.56 1.52 The statistics show that job satisfaction, organisational commitment and work stress were highest among respondents who are supervisors at their work place. Task 3 a) Test for equality of means   t df Sig. (2-tailed) Job satisfaction -2.66 308 0.008 Organisational commitment -1.709 308 0.088 Work Stress -1.431 306 0.153 b) The results of the T test show that at 5% level of significance, the difference between supervisors and workers in terms of job satisfaction is significant where it’s not significant for organisational commitment and work stress.

This means that supervisors and workers share different attitudes towards their job satisfaction ( Mendenhall & Sincich, 2006). c) Pearson correlations Job satisfaction Organisational commitment Work Stress Job satisfaction 1 .529(0.000) -.200(0.000) Organisational commitment .529(0.000) 1 -.272(0.000) Work Stress -.200(0.000) -.272(0.000) 1 The results show significance of the Pearson pair wise correlations between job satisfaction, Organisational commitment and Work Stress though the correlations are not strong.

Job satisfaction and Organisational commitment are positively related whereas job satisfaction and Work Stress are negatively related. Organisational commitment and Work Stress are also negatively related. d) The results indicate the both workers and supervisors share similar attitudes towards organisational commitment and work stress and as work stress increases, organisational commitment reduces. This means that management should improve the working conditions so as to boost the attitude of their staff.
