It helps HR professionals identify trends and anomalies in data, such as employee satisfaction scores or turnover rates, allowing for informed decision-making. By understanding the degree of variation, HR can implement targeted interventions to improve workforce stability and productivity. Additionally, it aids in assessing training effectiveness and evaluating recruitment processes.
