the sat test standard deviation values for 2015\u00a0is 116 points for critical reading, 120 points for math, and 115 points for writing. more 2015 standard deviation values based on different groups of students (think: race, gender, grade in school, etc.) can be found in this report<\/a> by the college board. unfortunately, the new sat test standard deviation values for the march sat aren’t released; in fact, the college board probably won’t release new sat test standard deviation values and other test statistics until the end of the year.<\/p>\n standard deviation is a measure of variation or differences between data points in a data set. it is a measurement that shows how spread out the data is in relation to the mean. a big standard deviation means that data is really spread out while a small standard deviation means that the data is grouped closer to the mean (and the way we know if standard deviation is big or small is by comparing two data sets).\u00a0standard deviation is really important on the sat because it helps create the sat scoring system and it also helps check that the scoring system is fair.<\/p>\n if you’ve taken the sat or the psat, you’ll notice that your report always has a percentile<\/a> with your score, which shows how well you did in comparison to the other students that took the test. this is because the sat is the type of standardized test<\/a> that creates its scoring based on trends found in general populations, which can be statistically represented by a\u00a0bell curve:<\/p>\nokay, that’s cool i guess…but what is sat test standard deviation and why do i need to know this?<\/h2>\n
