Psychosocial Interventions In Workplace – Assignment

20 May Psychosocial Interventions In Workplace – Assignment

An experiment was conducted to determine if motivational techniques in management significantly impacted employee stress levels compared to no intervention. An employee survey was given to three groups: one group under a manager who started using a transformational motivation technique, one group under a manager who began using a transformational motivation technique, and then a control group with no new technique used. Stress levels were self-reported by the employees as shown below. Use alpha = 0.05

 

 

 

Transformational	Transactional	Control
0	2	6
7	5	5
3	3	8
5	0	9
2	1	5

 

 

 

1. What is your null hypothesis?

 

 

 

2. What is your alternative hypothesis?

 

 

 

3. After running the single factor analysis of variance on the data, what is the p-value for between groups?

 

 

 

4. Using the 95% significance level, is there a significance difference in stress levels between the three groups? Yes or No

 

 

 

5. Do you reject or accept the null hypothesis? Reject Accept

 

 

 

Chi-Square Test for Independence

 

 

 

Using Chi-Square, we are looking to see if there is a significant difference between what we would expect results to be, and what the actual results were. That is, expected vs. observed. Use alpha = .05

 

 

 

Listed below are data from a survey conducted recently where Males and Females responded to their happiness with their supervisor (this is fictitious data).

 

 

 

Response	Male	Female	Total
Not at all	23	25	48
Somewhat	13	22	35
Very	26	16	42
Total	62	63	125

 

1. What is your null hypothesis?

 

 

 

2. What is your alternative hypothesis?

 

 

 

3. What is the Chi-Square value?

 

 

 

4. Is there significance evidence that a difference exists between the actual males and female responses in this sample and the expected mal
