1. Pearson Chi-Square Test
Variables
- X: Anxiety
- Y: Voltage
Hypotheses
- H0: Anxiety is not associated with stress.
- H1: Anxiety is associated with stress.
Results
- P-value: 0.0021
- Decision: There is insufficient evidence to conclude that anxiety is associated with stress, considering a 1% significance level.
2. Pearson Correlation Analysis
Variables
- X: Current Salary
- Y: Starting Salary
Hypotheses
- H0: Current Salary is not associated with starting salary.
- H1: Current Salary is associated with starting salary.
Results
- P-value: 0.000
- Decision: There is insufficient evidence to conclude a significant correlation between starting salary and current salary, considering a 1% significance level.
3. Levene's Test for Homogeneity of Variances
Variables
- X: Level of education group A
- Y: Level of education group B
Hypotheses
- H0: The variance in the educational level of group A is equal to the variance in the educational level of group B.
- H1: The variance in the educational level of group A is different from the variance in the educational level of group B.
Results
- P-value: 0.000
- Decision: There is insufficient evidence to conclude a significant difference between the variances in the educational levels of groups A and B, considering a 1% significance level.
4. Independent Samples Mean Comparison Test
Variables
- X: Level of education group A
- Y: Level of education group B
Hypotheses
- H0: The mean educational level of group A is equal to the mean educational level of group B.
- H1: The mean educational level of group A is different from the mean educational level of group B.
Results
- P-value: 0.000
- Decision: There is insufficient evidence to conclude a significant difference between the average educational levels in groups A and B, considering a 1% significance level.
5. Normality Testing
Variables
- X: Current Salary
- Y: Starting Salary
Test 1: Current Salary Normality
- H0: Current Salary is normal.
- H1: Current Salary is not normal.
Kolmogorov-Smirnov Test
- P-value: 0.345
- Decision: There is evidence to support that the Current Salary variable is normal, with a 1% significance level.
Shapiro-Wilk Test
- P-value: 0.456
- Decision: There is evidence to support that the Current Salary variable is normal, with a 1% significance level.
Test 2: Current Salary Normality (Re-evaluation)
- H0: Current Salary is normal.
- H1: Current Salary is not normal.
Kolmogorov-Smirnov Test
- P-value: 0.120
- Decision: There is evidence to support that the Current Salary variable is normal, with a 1% significance level.
Shapiro-Wilk Test
- P-value: 0.152
- Decision: There is evidence to support that the Current Salary variable is normal, with a 1% significance level.
