Quizplus · Accepted Answer

The unit of measurement used to assess where any score falls in a normally distributed trait is the standard deviation. The mean gives us an idea of the central tendency of the distribution, but the standard deviation tells us how spread out the scores are around the mean. Variability is related to standard deviation but is not the unit of measurement. Correlation coefficient is a measure of the strength and direction of the relationship between two variables and is not directly related to normal distribution.
