HOW DOES IT WORK?
To be able to calculate standard scores from scaled scores, you need to know:
What is the mean of your scaled score data?
i.e., If you are working with the results from a school quiz, the mean would be the average score of all of them. Add them all up and divide by the number of scores.
What is the standard deviation of your scaled score data?
You need to calculate the mean, subtract the mean to each number, and square the results. Calculate the mean of that results, and calculate its square root. You can also click on our Standard Deviation Calculator, and we will do all of that for you.
Finally, you just need to introduce the scaled score that you want to transform into the 'Scaled Score to transform' slot.
WHAT IS A SCALED SCORE?
What is a scaled score and its definition
A scaled score is the transformation of a raw score into a new scale. We use this process to make those scores easier to be understood, specially when we compare them to scores measured using different scales. What we do when we scale scores, is transforming those scores into a new scale. We apply certain operations on those numbers and then obtain results in our new scale.
There are several reasons why Standardized Testing Programs report scaled scores. The main reason is because we can then do a fair comparison between people's results. We can say that standardization leads to fairness. Understanding a scaled score is not always an easy task. You might have to find different definitions. On this website you will find all the resources you will need. Use them wisely!
Scaled score to standard score in the AP statistics exam and scores of college-bound students (ages 17-24). Additional conditions were included to investigate the impact of independent variables (age, race/ethnicity, socio-economic status, perceived academic stress) on AP statistics students' choice to take an extra credit course versus an unpaid course.
Results: Standardized mean of the AP statistics test scores were not significantly different from those of the students in our sample (P < .001). There were significant differences between the college-bound students and the unaffiliated (P < .01) and those in our sample (P < .01) on a majority of measures of mathematics, science, and reading, and no significant difference in vocabulary or science were found.
An AP statistics online course is the solution. The course provides information about all AP statistics available on the web (courses, exams, review guides, fact sheets, etc.) and includes test-taking tips and guides.
WHAT IS A STANDARD SCORE?
A Standard Score is a score that has certain characteristics. If you want to learn more about it, you should read all the necessary details on this page called Scaled Score vs Standard Score.
