A mean can be zero when the sum of the values in a dataset equals zero. This can occur if there are positive and negative values that cancel each other out. For example, in the dataset {-3, -1, 1, 3}, the sum is 0, resulting in a mean of 0 when divided by the number of values. Thus, the mean reflects the balance of the data around zero.
