 Statistical fluctuations

Statistical fluctuations refer to the variations or changes in a measurable quantity or phenomenon that occur due to randomness or inherent variability in a process. These fluctuations are often observed in statistical data collected from experiments, observations, or samples, and they can arise from various sources, including sampling error, measurement error, and intrinsic randomness in the underlying system being studied. In many cases, statistical fluctuations are characterized by their distribution properties, such as mean, variance, and standard deviation.
