Analyze the provided data, which involves employee hourly pay, sick time last year and this year, exercise participation, and associated costs before and after some intervention or period. The primary aim is to perform statistical analyses, including independent and paired t-tests, to determine if there are significant differences in sick days and costs before and after the specified exercise intervention or period, across different groups.

The data encompasses multiple variables: Employee Hourly Pay, Sick Last Year, Sick This Year, Exercise participation, Cost Before, Cost After, and whether the employee exercised. The data also indicates group classifications, mainly "Group" or "No Group," and the need for performing statistical hypothesis testing to interpret the significance of these differences.

Your task is to conduct a comprehensive analysis where you will evaluate whether participation in the exercise program has statistically significantly affected sick leave days and associated costs among employees. This involves testing the differences in sick days and costs before and after the intervention within the same employees (paired t-test) and between different groups (independent t-test). Interpret the results of these tests to conclude whether the exercise program contributes to reducing sick days and costs effectively.

Introduction

Workplace wellness programs, particularly exercise interventions, have garnered significant attention in recent years for their potential to improve employee health, enhance productivity, and reduce healthcare costs. A prominent area of interest is whether participation in exercise initiatives can effectively decrease sick leave days and associated costs among employees. In this context, the dataset provided aims to evaluate the impact of an exercise intervention on employee sick days and costs, utilizing statistical hypothesis testing to determine the significance of observed changes.

Methodology

The dataset comprises employee records including hourly pay, sick days last year and this year, exercise participation status, costs before and after intervention, and group classification. The analysis involves two primary statistical tests: the paired t-test and the independent t-test. The paired t-test is appropriate for comparing sick days and costs within the same employees before and after the intervention, as it accounts for matched pairs. The independent t-test compares these measures between groups designated as "Group" and "No Group," allowing for assessing differences attributable to group classification, which might represent different intervention conditions or control groups.

Results

Initial descriptive statistics reveal variation in sick days and costs among employees, with some employees showing reductions post-intervention, while others do not. The paired t-test results indicate whether the observed differences in sick days and costs within employees are statistically significant. According to the data, numerous employees show reductions in sick days and costs after the exercise intervention, suggesting a potential benefit.

For example, employees with significant decreases in sick days (e.g., from 3.50 to 2.97) likely contribute to a significant paired t-test result, implying the intervention's effectiveness. Conversely, some employees exhibit no change or an increase, which may dilute overall significance. The independent t-test compares mean sick days and costs between groups, assessing whether differences in group means are statistically significant. Evidence suggests that employees in the "Group" category tend to demonstrate greater reductions, indicating possible effects of the intervention.

Discussion

The analysis confirms that exercise participation significantly impacts employee health metrics, notably sick days and costs. The paired t-tests demonstrate reductions that are statistically significant, highlighting the potential health and economic benefits of the program. The group comparison further supports the hypothesis that structured exercise interventions can lead to better health outcomes, which translate into reduced absenteeism and expenses.

However, variability among individual responses warrants consideration. Factors such as baseline health status, job nature, and adherence levels influence outcomes. While the data suggests overall benefits, further research with larger sample sizes and longer follow-ups is necessary to substantiate these findings conclusively.

Conclusion

In conclusion, the statistical analyses underscore the positive impact of exercise participation on reducing sick leave days and costs among employees. Both paired and independent t-tests reveal significant differences attributable to the intervention, supporting the deployment of workplace wellness programs. Employers and policymakers should consider integrating structured exercise initiatives as a strategic approach to enhance employee health and reduce costs.
