Answer 1

Option D) The number of standard deviations a measurement is from the mean

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.
• $z = \displaystyle\frac{x-\mu}{\sigma}$
• It is known as standardization or normalization.

Thus, standard score can be defined as:
