Question

The deviation of a value (x) from the mean of the sample divided by the standard deviation (s)of the sample is known as the "z" value or z-score.
1. True
2. False

Answer 1

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:

     $z = \dfrac{x-\mu}{\sigma}$

  x is the value

 μ is the mean

 σ is the standard deviation

Hence, the statement given is true.
