Using the normal distribution, it is found that the median of the MCAT scores was of 500.9.
<h3>Normal Probability Distribution</h3>
In a normal distribution with mean and standard deviation
, the z-score of a measure X is given by:
In this problem, the mean score was 500.9, hence the median score was also of 500.9.
