Answer: 0

The z score is the value of the random variable associated with the standardized normal distribution (mean = 0, standard deviation =1). Now, the median and the mean of a normal distribution are the same. The 50 percentile z score = the median = mean = 0.

What is the normal IQ range?

The IQ, or intelligence quotient, is actually a bell curve* statistic whereby the score of 100 is dead centre meaning that half of the normal distribution falls below 100 and half fall above 100. Understand that this is not the average but the median. The median is exactly the 50th percentile, exactly. This may seem like a poor score but the bell curve has a maxima at this point so this is at least very close to where most people score. In fact, on both ends of the curve, the distribution falls rapidly off around a score of 90 on the lower end and around a score of 110 on the high end. Most websites such as IQ Basics* do consider a score between 90 and 110 to be a normal score. See the related links for more info on the highlighted topics
