Stanine (STAndard NINE) is a method of scaling test scores on a nine-point standard scale with a mean of five and a standard deviation of two. Some web sources attribute stanines to the U.S. Army Air Forces during World War II.

2021年1月1日 · A stanine score, short for “standard nine” score, is a way to scale test scores on a nine-point standard scale. Using this method, we can convert every test score from the original score (i.e. 0 to 100) to a number between 1 and 9.

A stanine (“standard nine”) score is a way to scale scores on a nine-point scale. It can be used to convert any test score to a single-digit score. Like z-scores and t-scores, stanines are a way to assign a number to a member of a group, relative to all members in that group.

What are stanines, percentiles, and grade equivalent scores? Stanine is short for standard nine. A stanine score ranges from a low of 1 to a high of 9; therefore, the name “stanine.” For instance, a stanine score of 1, 2, or 3 is below average; 4, 5, or 6 is average; and 7, 8, or 9 is above average.

The meaning of STANINE is any of the nine classes into which a set of normalized standard scores arranged according to rank in educational testing are divided, which include the bottom 4 percent and the top 4 percent of the scores in the first and ninth classes and the middle 20 percent in the fifth, and which have a standard deviation of 2 and ...

1. Explain the word stanine. 2. Given the standard normal distribution, compute the probabilites. a. p(-1.75 z -.25) b. p(z is not in the interval -1.75 z -.25) c. p(z -1.25) 3. Given a normal distribution with a mean of 65 and a standard deviation of 10, a. estimate p(52.5 x 62.5) b. 1 - …

2018年3月13日 · Stanine scores are used in education to compare student performance over a normal distribution. Stanine scores convert raw test scores to a one-digit whole number to simplify test interpretation. Typically, stanine scores between 4 and 6 are considered average, scores of 3 or less are below average while scores of 7 or greater are above average.

A stanine is a type of standardized score, used to compare the position of a single score to a distribution of scores, on a scale of 1–9. Like other standardized scores, such as percentiles, T scores, and z scores, stanines are derived from a transformation of raw scores based on an assumption of normally distributed data.
