What does a standard score measure?

a. the number of standard deviations that are present under a normal curve
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

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. 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
