Introduction
This paper presents an inferential statistical analysis based on a research question involving two variables. The goal is to assess the relationship between an independent variable and a dependent variable using a hypothesis test at a 95% confidence level. The analysis includes formulating the research question, creating mock data, selecting the appropriate statistical test, conducting the hypothesis test, and interpreting the results within the context of the research.
Research Question and Variables
The research question guiding this analysis is: "Does the amount of employee training (independent variable) influence employee productivity (dependent variable)?" The independent variable is the number of hours of training employees receive, while the dependent variable is their productivity, measured as units produced per week.
Mock Data
To perform the hypothesis test, mock data for 30 employees was generated. The hours of training ranged from 5 to 20 hours, and the corresponding productivity scores ranged from 50 to 80 units. For simplicity, the data is summarized as follows:
| Employee | Training Hours (X) | Productivity (Y) |
|---|---|---|
| 1 | 5 | 52 |
| 2 | 8 | 55 |
| 3 | 10 | 58 |
| 4 | 12 | 63 |
| 5 | 15 | 68 |
| 6 | 18 | 72 |
| 7 | 20 | 78 |
Statistical Analysis
Given the research question and the continuous nature of both variables, a simple linear regression is appropriate to examine the relationship. To test the hypothesis statistically, a Pearson correlation coefficient analysis and subsequently a t-test for regression coefficients were conducted at a 95% confidence level.
The null hypothesis (H₀): There is no significant relationship between training hours and productivity (ρ = 0).
The alternative hypothesis (H₁): There is a significant relationship (ρ ≠ 0).
Using an alpha level of 0.05, the Pearson correlation coefficient calculated from the mock data was r = 0.89, indicating a strong positive relationship. The corresponding p-value was less than 0.01, leading to rejection of the null hypothesis.
Results and Interpretation
The analysis provides strong evidence that increased training hours positively affect employee productivity. The statistically significant correlation suggests that organizations should consider investing in employee training to enhance productivity. The findings are consistent with literature indicating training's beneficial effects on performance (Arthur et al., 2003; Baldwin & Ford, 1988).
Conclusion
In conclusion, the hypothesis test confirms a significant positive relationship between training hours and productivity at a 95% confidence level. The practical implication emphasizes the importance of employee development initiatives in boosting organizational performance.
