B. the number of standard deviations a measurement is from the highest value
C. the number of standard deviations a measurement is from the lowest value
D. the number of standard deviations a measurement is from the mean

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:

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