Statistical analysis

Definition

Statistical analysis is the process of collecting, reviewing, analyzing, and drawing conclusions from data. It allows researchers to identify patterns, relationships, and trends within datasets, facilitating better decision-making. In computational fluid dynamics and numerical simulations, statistical analysis helps in understanding complex behaviors in nanofluidic systems by quantifying the impact of various parameters on system performance.
