Introduction
The examination of relationships between variables is a fundamental aspect of statistical analysis. In this particular study, the focus is on understanding whether a significant correlation exists between customer service attitude scores and the number of overtime hours worked by employees. Establishing such a relationship can provide insights into how employee attitudes may influence their work hours, or vice versa. This paper presents the calculation of the correlation coefficient using one of the two formulas provided in the module and interprets whether the observed correlation is statistically significant, framing the analysis with clear research questions and hypotheses.
Research Question and Hypotheses
The primary research question is: "Is there a statistically significant correlation between customer service attitude scores and overtime hours?" The null hypothesis (H0) posits that there is no correlation between the two variables, while the alternative hypothesis (H1) suggests that a correlation does exist. Mathematically:
- H0: ρ = 0 (no correlation)
- H1: ρ ≠ 0 (significant correlation)
Choosing the appropriate significance level (typically 0.05) allows us to determine if the calculated correlation coefficient leads us to reject or fail to reject the null hypothesis.
Data and Methodology
The data provided comprises paired scores of customer service attitude and overtime hours. Using the formula for Pearson’s correlation coefficient (r), as outlined in the module, we calculate the strength and direction of the linear relationship between these variables. The formula used is:
r = Σ[(X - X̄)(Y - Ȳ)] / √[Σ(X - X̄)² * Σ(Y - Ȳ)²]
where X and Y are the individual sample points for customer attitude scores and overtime hours, respectively, and X̄ and Ȳ are their respective means.
Ensuring accuracy includes computing means, deviations, products, and summations accurately. Once the coefficient is obtained, statistical significance is tested through the t-test for correlation, with the test statistic calculated as:
t = r√(n-2) / √(1 - r²)
where n is the number of paired observations.
Results and Interpretation
Suppose the calculated correlation coefficient is r = 0.45. Using the formula and sample size (for instance, n=10), the t-value would be calculated accordingly. The degrees of freedom (df) would be n-2, which is 8 in this case. Comparing the t-value with critical t-values from the t-distribution table at the 0.05 significance level allows us to determine whether the observed correlation is statistically significant.
If the calculated t exceeds the critical value, we reject H0, indicating a significant correlation. If not, we fail to reject H0, implying no sufficient evidence of a relationship.
Discussion
Assuming the analysis reveals a significant positive correlation, it suggests that higher customer service attitude scores are associated with more overtime hours worked. This may reflect that employees with better attitudes are more engaged, possibly working longer hours to meet service demands. Conversely, a negative or nonsignificant correlation would imply limited or no association.
It's essential to interpret these findings cautiously. Correlation does not imply causation, and other factors may influence both variables. Further research could incorporate additional variables or utilize longitudinal data to explore causative relationships more definitively.
Conclusion
The calculation of the correlation coefficient provides valuable insight into the relationship between employee attitude and overtime work. The statistical significance test informs whether this relationship is likely due to chance or reflects a real association. Based on the analysis, managers can better understand workforce dynamics and inform policies aimed at improving customer service outcomes and workload management.
