常见问题
What is a Test Score Percentile Calculator?
This tool calculates the percentile rank of a specific test score based on a normal distribution. It tells you what percentage of test-takers scored lower than you.
What data do I need to use this calculator?
You need three values: your raw test score, the mean (average) score of the group, and the standard deviation of the group.
What does the result mean?
The result represents the percentage of the population that falls below your score. For example, a result of 85 means you scored higher than 85% of the group.
Why is Standard Deviation required?
Standard deviation measures how spread out the scores are. It is necessary to convert your raw score into a standardized 'Z-score' before finding the percentile.
What if I don't know the Mean or Standard Deviation?
You cannot use this calculator without the mean and standard deviation. These statistics are usually provided by the exam board or instructor after the test is graded.
Does this work for any type of test?
This calculator assumes the test scores follow a 'Normal Distribution' (bell curve). It works best for standardized tests like IQ tests or SATs, but may be inaccurate for skewed distributions.
