The Z-score measures how many standard deviations a particular value is from the mean of a distribution. However, if the standard deviation of the distribution is 0, then the Z-score formula would involve division by 0, which is undefined. Therefore, the Z-score does not make sense for the value of 1 or any other value when the standard deviation is 0. In such cases, other measures of relative position, such as percentiles or quartiles, would be more appropriate for describing the position of a value within the distribution. **
