What types of data are age equivalent and grade equivalent scores?

Age equivalents, grade equivalents, and percentile scores all represent ordinal scales. Level of measurement in which numbers are assigned with the assumption that each number represents a point that is an equal distance from the points adjacent to it.

What type of data is age and grade equivalents?

Age equivalents are ordinal data, which means there are not equal units between scores. The development curves are higher in younger children and plateau with older children and adults. Because of this, there are larger differences between scores of younger as compared to older children.

What is the age grade equivalent score?

An age or grade equivalent is simply the median raw score for a particular age or grade level. Because the acquisition of skills measured by an instrument such as a vocabulary test occurs more rapidly during early ages, raw scores increase at a greater rate with younger examinees than with older examinees.

What is a grade equivalent score in education?

GRADE-EQUIVALENT SCORES

The Grade-Equivalent score compares your child's performance on grade-level material against the average performance of students at other grade levels on that same material and is reported in terms of grade level and months.

Are age equivalent scores misleading?

These types of scores are often very misleading though because this does not mean the child is functioning at the level of a 3-year-old. Since 68 is the median score, it is necessary that children will score above and below without being outside of normal limits.

AssessMinutes - Understanding Grade Equivalent scores

What is the problem with grade equivalent scores?

Grade equivalents are not standardized scores (which are psychometrically sound and are reported) meaning that variance can exist from test to test or even within the test assessing different skill sets (math vs. reading).

Should age and grade equivalents be reported as a reliable measure of performance?

Age-equivalent and grade-equivalent scores are not considered a reliable measure and should generally not be used.

Why are age and grade equivalent scores misleading?

AE scores compare children to the “average x-year-old.” However, the average x-year-old does not exist. Rather, the term average represents a range of performance for a particular age group. A third serious limitation of AE scores is the lack of information they provide about a test taker's performance on a given test.

What is grade equivalent in statistics?

Grade equivalent scores can be calculated for a test by finding the median (i.e., the 50th percentile) score obtained by children at each grade level on that test. Children who earn the median raw score for a given grade level are assigned a score equivalent to that grade level.

What is an example of an age equivalent score?

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 is an example of a grade equivalent score?

For example, assume the mean score for ninth graders in the third month ofschool (9.3) is 50 on the ninth grade version of the test. If a sixth gradergets a 50 on the sixth grade test, he receives a grade-equivalent score of 9.3even though the sixth grader took the sixth grade version of the test.

What is an age based scale?

a system for expressing test scores in terms of the chronological ages at which the scores are typically obtained.

What is the difference between grade level and grade equivalent?

The grade equivalent represents the grade level and month of the typical (median) score for students. For example, a fifth grade student who earns a 5.9 on a norm-referenced test has earned a score similar to the 50th percentile students in the test's norming group who were in their ninth month of fifth grade.

What type of data is age data?

Is age an interval or ratio? Age is typically considered to be measured on a ratio scale. This is because age has a true zero point, which means that a value of zero represents the absence of age.

What type of data is age?

Depending on the question, age can be a nominal or ordinal variable. If the question is "How old are you?" it's a nominal variable. If the question is "What age range are you in?" it's an ordinal variable.

What type of data is a grade?

Ordinal (e.g., extent of agreement, school letter grades)

How do you calculate grades in statistics?

To calculate a test grade, you need to know the total number of points possible and the number of points earned. The test grade is then calculated by dividing the points earned by the total points and converting this to a percentage or a letter grade.

What is a grade equivalent in Woodcock Johnson?

A grade equivalent (GE), or grade score, likewise reflects the client's performance in terms of the grade level of the norm- ing sample at which the average score is the same as the client's raw score.

Should I use age or grade based norms?

In general, for students who are in the appropriate grade for their age, grade-based norms yield scores that are not educationally significant, while grade-based standard scores for students who are young for their grade placement are lower than age-based standard scores and grade-based standard scores are higher than ...

Is a type of standard score that is often seen when doing psychoeducational assessments?

Scaled Score: Psychoeducational tests are typically made of several mini-tests, or subtests, which assess specific skill areas. Scaled scores are used to report subtests scores. Scaled scores are standard scores that have a mean of 10 and a standard deviation of 3.

How do you explain grade equivalent scores to parents?

A grade equivalent indicates the grade level, in years and months, for which a given score was the average or middle score in the standardization sample. For example, a score of 25 with the grade equivalent of 4.6 means that, in the norm group, 25 was the average score of pupils in the sixth month of the fourth grade.

Do colleges like standards based grading?

Letter grades and transcripts based on standards are acceptable, if not preferable, by admissions folks, with a few caveats. When universities receive profiles/transcripts from schools with alternative grading/reporting systems, these students receive equal consideration.
