An inferential model is a statistical tool used to make predictions or draw conclusions about a larger population based on a sample of data. It helps researchers understand relationships between variables and assess the likelihood of certain outcomes. By analyzing patterns in the sample, the model can infer characteristics of the entire population, which is often impractical to study directly. These models are commonly used in various fields, including economics, psychology, and healthcare. They rely on techniques such as hypothesis testing and regression analysis to provide insights and guide decision-making.
