What is a score of 468 converted to percentile on the millers analogy test?
MAT scores are normally distributed with a mean of 400 and a standard deviation of 25. z = (468-400)/25 = 2.72 Pr { N <= 2.72 } ~= 0.9967 IOW, percentile is about 99.67.
What percentile does a score of 351.5 on MAT equate to?
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.)
What is the percentile rank of the score 20 in a unit normal distribution that has a population mean of 21 and a variance of 4?
It is the 31st percentile.
Which measure is always the 50th percentile Mean Meadian or Upper Quartile?
Mean.
What is the score?
When a student takes a test or examination the result they receive, as a number, is often called a score. The average of a collection of scores, say for one class of students, is called a mean score. Mean is just another word for average.

Who would use mean median and mode?
I use it in class when looking at my student's scores... Often I look at mean, median, and mode to decide to reteach a concept or not.
The mean of a distribution of scores is the?
The mean of a distribution of scores is the average.
Is the mean 50 percentile of any normal distribution?
Yes, the mean (and median and mode) is the 50th percentile of any normal distribution.
Recalling that SAT scores are always expressed as multiples of 10 how many points did you get on the test?
SAT scores are normally distributed, with a mean of 500 points and a standard deviation of 100 points. Suppose you take the SAT. Several weeks later, you receive your results, which show that you reached the 90th percentile for the math portion.

What is the Difference between z scores and percentile ranks?
First let's define both, that will help to see the difference.1.A percentile is a measure that lets us know what percent of the total frequency scored below that measure. A percentile rank is the percentage of scores that fall below a given score. Here is how that works.Given a score, call it S and a total of n scores we are looking at, we find the number of scores below S and divide that by n. Next multiply that by 100 and you have the percentile rank.Now a z score is the number of standard deviations from the mean.Say the mean is M and your score is S as above. Let sigma be the standard deviation of the distribution. Then z=(S-M)/sigma.So let's say the mean M is 100 and sigma is 15. S is 132, you did better than average!So z=(132-100)/15=2.13If 60 percent of the people scored less than you, then you are in the 60th percentile.Furthermore, lets say, there were 100 people taking test, then 60 of them scored less than you. Your percentile ranking is (60/100)x100=60So both are measures of where your results falls in a distribution. z scores are often used for probability of a certain result. Percentile ranks are often used in looking at standardized test results or growth data. One can convert from one to the other.I have given a conversion table link belowhttp://www.acposb.on.ca/conversion.htm
What does the 35th percentile mean?
