What A statistic that tells the number of standard deviations a data value is above or below the mean is called?

The statistic that indicates how many standard deviations a data value is above or below the mean is called the z-score. It is calculated by subtracting the mean from the data value and then dividing by the standard deviation. A positive z-score indicates the value is above the mean, while a negative z-score indicates it is below the mean. This standardization allows for comparison across different datasets.
