It means that the number is negative. Negative numbers are always under 0.
The mean is calculated by dividing the sum of a set of values (the dividend) by the number of values in that set (the divisor). The sign of the quotient, or the mean, will depend on the sign of the dividend because the divisor (the count of values) is always positive. If the sum of the values is positive, the mean will also be positive; if the sum is negative, the mean will be negative. Thus, the sign of the mean directly reflects the sign of the sum of the values.
