The third step is to analyze the data you have collected to uncover patterns, trends, and insights that can help you make better decisions. Depending on the goal and scope of your analysis, you can use various techniques and metrics. For example, descriptive analysis can be used to summarize and visualize the data using statistics, charts, graphs, and dashboards. Inferential analysis can help test hypotheses and draw conclusions from the data using correlation, regression, and significance testing. Predictive analysis can forecast future outcomes and scenarios from the data using machine learning, artificial intelligence, and simulation. And prescriptive analysis can recommend optimal actions and solutions from the data using optimization, decision analysis, and game theory. Additionally, some common metrics to measure and evaluate recruitment and retention efforts are recruitment metrics such as time to hire, cost per hire, quality of hire, source of hire, and applicant conversion rate; as well as retention metrics such as turnover rate, retention rate, employee engagement, employee satisfaction, and employee net promoter score.
