2. Variable Selection for Analysis Sample 9

3. Sample 9
Data View
Number of
Individual data: 57

4. Educational Level Skewness: .040/.316 = 0.126 (between -1.96 to +1.96)
Kurtosis: .066/.623 = 0.106 (between -1.96 to +1.96)

6. Lowest Education level 8 years
25% of the employee have 12 years of
Education
75% of the employee have 16 years
Education
Highest Education Level 21 years

7. Beginning Salary
Skewness:
1.939/.316 = 6.136 (not between -1.96 to +1.96)
Kurtosis:
3.764/.623 = 6.041 (not between -1.96 to +1.96)

8. Mode 12

9. 25% of the Employee get $ 12,450
as their Beginning Salary
75% of the Employee get $ 18,750
as their Beginning Salary

10. Correlation Analysis
 Education Level
 Beginning Salary

11. Independent Variable : Education Level
Dependent Variable : Beginning Salary
R Square= 43% , So 43% of the variability of Beginning Salary can be
explained through educational level
Coefficients of Determiner

12. Linear Relationship in Graphs

14. Regression Analysis
If the educational level increased by 1 year the beginning salary will be increased by
1757.943 dollars.
The educational level significantly influences the beginning salary

15. Let,
Ho: µ=21,000, Ha: µ < 21,000
Since the significance value is less than 0.05 , so it
can be said that there is enough evidence to reject
null hypothesis.
HypothesisTesting of Beginning Salary

16. Hypothesis Testing of Educational Level
Let,
Ho: µ=16, Ha: µ ≠16
Since the significance value is less than 0.05 , so it can be said that there
is enough evidence to reject null hypothesis.
