Answer:
true.
Explanation:
z-score gives an idea of how far the value of data is from the mean point. Basically is the measure of a standard deviation below or above the mean.
More the deviation of the data from the mean more is the standard deviation.
Z-score or value is calculated by the expression given below:
[tex]z = \dfrac{x-\mu}{\sigma}[/tex]
x is the value
μ is the mean
σ is the standard deviation
Hence, the statement given is true.
