ABSTRACT This paper presents an effective approximation method for analyzing a stochastic system composed of interacting components for large . By assuming linear interactions and considering the ensemble average, we demonstrate that the system can be accurately approximated by a one‐dimensional model. Furthermore, the approximation reveals the distinct influences of interaction and noise on the system's dynamics: While the interaction enhances metastability, the noise contributes to stabilizing the system.
