## Question 372:

1## Answer:

No answer provided yet.For z-score and cumulative percentiles see the page on the interactive graph of the standard normal curve. If you know the mean and standard deviation of the scaled scores (usually it's 500 and 100) you can enter those into the normal curve graph. Not sure where there is information on the t-score equivalents of SAT scores. Keep in mind the difference between z and t-scores is that t-scores account for the size of the sample, where z-scores use the population.

See the wikipedia entry on the percentiles and more information on SAT scaling.
