What percentage of the area under the normal curve lies between µ - 3s and µ 3s?
Just so, what percent of the area underneath this normal curve is shaded?
The shaded area contains 95% of the area and extends from 55.4 to 94.6. For all normal distributions, 95% of the area is within 1.96 standard deviations of the mean.
Also, what does a standard score measure? Standard scores. The standard score indicates how many standard deviations an observation is above or below the mean: the standard deviation is the unit of measurement of the z-score. It allows comparison of observations from different normal distributions, which is done frequently in research.
Subsequently, question is, what is the value of the standard score for the mean of a distribution?
The standard score for the mean is 0. The standard score is the signed number of standard deviations that a score is away from the mean. By definition, the mean is 0 sd from the mean.
Which is greater in a normal distribution the mean or the median explain?
The mean; in a normal distribution, the mean is always greater than the median. The median; in a normal distribution, the median is always greater than the mean.
