It depends on the underlying distribution. If Gaussian (standrad normal) then the percentile is 77.
approximately 32nd percentile
The top percentile is 100. It represents the maximum score.
The 95th percentile represents an IQ of about 125.
The Miller Analogies Test scores have a mean of 400 and a standard deviation of 25, and are approximately normally distributed.z = ( 351.5 - 400 ) / 25 = -1.94That's about the 2.6 percentile.(Used wolframalpha.com with input Pr [x < -1.94] with x normally distributed with mean 0 and standard deviation 1.)
It is -1.281551
approximately 32nd percentile
124
The top percentile is 100. It represents the maximum score.
To find what z-score represents the 80th percentile, simply solve for 0.8 = F(z), where F(x) is the standard normal cumulative distribution function. Solving gives us: z = 0.842
The 95th percentile represents an IQ of about 125.
The standardised score decreases.

It is -1.281551
The Miller Analogies Test scores have a mean of 400 and a standard deviation of 25, and are approximately normally distributed.z = ( 351.5 - 400 ) / 25 = -1.94That's about the 2.6 percentile.(Used wolframalpha.com with input Pr [x < -1.94] with x normally distributed with mean 0 and standard deviation 1.)
T-score is used when you don't have the population standard deviation and must use the sample standard deviation as a substitute.
score of 92
The absolute value of the standard score becomes smaller.
