LO1
This type of test compares an individuals score to the average scores of a peer group
what is norm-references test
Derived Scores convert an individuals raw test score into a... (Two options)
What is Percentile or a standard score
This type of IQ score shows how far someone’s intelligence score is from the average.
What is a Deviation IQ
This range of scores is where we would expect a person's score to fall if he or she took the instrument over and over again.
What's the Standard Error of Measurement?
What is the difference between standard error of measurement and standard error of estimate?
Standard error of measurement gives the confidence interval around an OBTAINED score, whereas standard error of estimate gives the confidence interval around a PREDICTED score.
Tests like SAT, ACT, and GRE are examples of this kind of referencing.
What is norm-referenced
Standard score that involves a mean of 0 and places test score within a standard deviation compared to mean
What is a Z - Score
A standard scoring systyem frequently used in schools
What is Staines
The degree to which a test is free of measurement error.
What is Reliability?
Interpret standard error of estimate in terms of variables.
Based on the scores received on one variable (e.g., SATs), standard error of estimate allows us to predict a range of scores an individual might obtain on a second variable (e.g., first-year college GPA).
In this type of test, your score is compared to a set standard or percentage, such as needing 70% to pass.
What is a criterion-referenced
The mean percentage on a percentile ranking scale
50%
These “standard ten” scores are often used on personality tests and range from 1 to 10.
What are Sten Scores
The raw score or the standard score.
What is the SD?
This is the most basic measurement scale, where numbers are assigned to categories like race without implying any order or magnitude.
What is the nominal scale?
Tests like a driver’s license exam or college writing exit exam use this type of referencing.
What is criterion-referenced
The formula for calculating a Z - Score
Z = X - M/ SD
a third-grade student scores at the same level as an average fourth-grader, their score is called this.
What is a grade equivalent?
The range in which the true score might fall.
What is the SEM?
This scale has equal intervals between scores but lacks a true zero point, such as scores on a depression inventory.
What is interval?
This federal law required schools to make sure all students reached a set level of proficiency on state tests, using predetermined passion scores.
What is No Child left Behind (NCLB)
One type of standard score that can be converted from a z-score
What is T-Score
This norm-referenced score is often used in education to show equal intervals across a bell curve.
What are Normal Curve Equivalent (NCE) Scores?
The more errors and the larger the range, where an individual's true score might fall.
This scale has equal intervals and a true zero point, allowing for statements like “twice as much.”
What is ratio?
