My understand says that a 93 percentile score means that amongst all of the test takers, your score is better than 93% of the other test scores. ... Assuming there were 100 test takers, if you get a rank of 93 implies you are ahead of 92 of the other test takers. Higher the rank, the better.

Percentile, however, refers to the number of other test takers' scores that an individual's score equals or exceeds. If a child answered 25 questions and did better than 50% of the children taking the test he would score at the 50th percentile.

Answer: It means that 85% of the scores were below your score and 15% of the scores were better than your score. ... The 70th percentile means that 70% of the scores were below your score, and 30% were above your score. Your actual score was 82%, which means that you answered 82% of the test questions correctly.

Percentile. A percentile is a value on a scale of one hundred that indicates the percent of a distribution that is equal to or below it. ... A 50th percentile is the same as a "median." An average, or "mean," is similar but a weighted result.

A 99% confidence interval is wider than a 95% confidence interval. In general, with a higher probability to cover the true value the confidence interval becomes wider. In contrast to p-values, confidence intervals indicate the direction of the effect studied.

Percentile is calculated by taking the product of your marks x 100 and divide this product by the highest mark obtained by the top ranker. This is how you calculate your percentile based on the marks. This is subject to variation since none of us know how much will be the highest marks.

You have two options for the confidence level: 95% or 99%. Note that is relation between the confidence level of the confidence interval and the precision of the estimate: A choice for a higher confidence level (99%) will lead to a wider confidence interval, and thus to a less precise estimate.

A percentage denotes a mathematical value taken out of 100, such as marks obtained in the exam by a student is 80%. The percentile will show rank-ordering out of others in a sample. For example, he has scored 40% more than other students.

If you get a composite SAT score of 1083 or more, you are above average. The 75th percentile composite SAT test score is 1215, the 90th percentile is 1340 and the 95th percentile is 1410. This table, which is based on College Board data, lists the percentile ranking for various composite SAT scores.

Improved data quality leads to better decision-making across an organization. The more high-quality data you have, the more confidence you can have in your decisions. Good data decreases risk and can result in consistent improvements in results.

Broadly, anything above the 50th percentile (median) can be considered a good score, and anything above the 75th percentile a great score. Using this definition, we can say that only some scores in this chart are good GRE scores—specifically, 151 or higher on Verbal and 153 or higher on Quant.

I now know this first hand :( I would say, looking at some of the sample questions, that the A Level examinations are quite a bit tougher than the AP. Especially given that you need to get about 80% on an AP test to score a 5 (which is the highest score).

The 25th percentile ACT score is 28, and the 75th percentile ACT score is 32. In other words, a 28 places you below average, while a 32 will move you up to above average. There's no absolute ACT requirement at Ohio State University, but they really want to see at least a 28 to have a chance at being considered.

Well, your composite ACT score corresponds to a percentile ranking that tells you how you did compared to all other test-takers. 20 is a 50th percentile, or average score.

If Ha contains a greater-than alternative, find the probability that Z is greater than your test statistic (look up your test statistic on the Z-table, find its corresponding probability, and subtract it from one). The result is your p-value. (Note: In this case, your test statistic is usually positive.)

To calculate a percentile score, the marks secured are converted into a scale ranging from 100 to 0 for each session of examinees. NOTE: Percentile score is not the same as the percentage of marks secured. It is the practice of comparing candidates' scores who appeared in different shifts of the exam.
