Answer:
Option D) The number of standard deviations a measurement is from the mean
Step-by-step explanation:
Standard Score:
- Standard score is also known as the z-score, z-value, normal scores or the standardized score.
- It tells us about the values of standard deviations by which the value of data point is above or below the mean value.
- The standard score for a data point may be negative or positive.
- It is obtained by subtracting the population mean from the data point and then dividing it by the population standard deviation.
- [tex]z = \displaystyle\frac{x-\mu}{\sigma}[/tex]
- It is known as standardization or normalization.
Thus, standard score can be defined as:
