A)subtract its mean and divide by its standard deviation.
B)integrate the area below two points under the normal distribution.
C)add and subtract 1.96 times the standard deviation to the variable.
D)divide it by its standard deviation, as long as its mean is 1.

Question

Quizplus · Accepted Answer

Standardizing a variable means converting it to a standard normal distribution where the mean is 0 and the standard deviation is 1. This is achieved by subtracting the mean from each observation and dividing by the standard deviation. Therefore, the correct choice is A. Option B refers to finding the area under the normal curve, and Option C only adjusts the range of the variable but does not standardize it. Option D lacks clarity and is not a commonly accepted method for standardizing a variable.
