What does stanine mean in test scores?

## What does stanine mean in test scores?

Stanine scores are derived from a national norm reference sample. A stanine is a score from 1 to 9 with a. stanine of 9 indicating a very high level of general ability relative to the whole norm reference group, and. a stanine of 1 indicating a very low relative achievement.

## What is stanine and percentile?

Stanine. Stanine(STAndard NINE) is a method of scaling test scores on a nine-point standard scale with a mean of five (5) and a standard deviation of two (2). Test scores are scaled to stanine scores using the following algorithm: Rank results from lowest to highest.

How is stanine calculated?

Calculation of Stanine Scores

1. The first 4% of ranked scores (raw scores 351-354) will be given a stanine score of 1.
2. The next 7% of ranked scores (raw scores 356-365) will be given a stanine score of 2.
3. The next 12% of ranked scores (raw scores 366-384) will be given a stanine score of 3.

### What is a stanine of 8?

Stanine scores of 7 or 8 are usually interpreted as indicating “above average” performance. And a stanine score of 9 is normally considered to reflect “outstanding” performance, for that’s the highest score one can get.

### How do you explain stanine score to parents?

A stanine is a score on a nine-unit scale from 1 to 9, where a score of 5 describes average performance. The highest stanine is 9; the lowest is 1. Stanines are based on the pattern of scores described earlier. Except for 1 and 9, they divide the baseline into equal amounts of the characteristic being measured.

How are percentile ranks and stanines used with standardized test scores?

The stanine scale is a normalized standard score scale consisting of nine broad levels designated by the numbers one through nine. A percentile rank indicates the percentage of students in the same age group whose scores fall below the score obtained by a particular student.

## What is the highest stanine?

9
The namestanine comes from “standard nine.” There are only 9 possible staninescores, whole numbers from 1 (lowest) to 9 (highest). Relating stanines to thenormal curve, each stanine score represents a wide band of raw scores andpercentile ranks.

## How do you find stanine from z-score?

Procedure to find stanine scores/convert data in stanine scores:

1. Find the mean µ of the data.
2. Calculate the standard deviation σ for the given data.
3. Covert the data into Z scores using the formula, Z=(X-µ)/σ
4. Replace the Z score value by the corresponding stanine score by using the below table.

How do you explain stanines to parents?

### How do you explain grade level equivalent scores to parents?

Simply put, an age equivalent is a comparison of your child’s performance compared to age groups whose average scores are in the same range. For example, if your 9-year-old child scores a 42 raw score on a test, and that score is average for 8-year-olds, their age equivalent score would be 8.

### What do percentile ranks mean?

A percentile rank indicates how well a student performed in comparison to the students in the specific norm group, for example, in the same grade and subject. A student’s percentile rank indicates that the student scored as well as, or better than, the percent of students in the norm group.

How do you interpret percentile rank?

Percentile ranks are often expressed as a number between 1 and 99, with 50 being the average. So if a student scored a percentile rank of 87, it would mean that they performed better than 87% of the other students in his norm group.
