The empirical rule assumes that the data is approximately symmetric and bell-shaped. This means that the distribution of data is roughly symmetrical around the mean, and the majority of the data falls within one, two, or three standard deviations of the mean. This assumption holds true for many real-world datasets, including those that are normally distributed or have a similar distribution shape.
