What are the two most commonly used scales in education?

Ordinal; Equal Interval


What kind of scale does this demonstrate: Abner, Allison, Andy, Astor

Nominal


What kind of scale does this demonstrate?
Abner: 4'9" Allison: 5'0 Andy: 5'3" Astor: 5'5" 
Equal Interval


What kind of scale does this demonstrate:
Abner: Intermediate Allison: Intermediate Andy: Above Average Astor: Excellent 
Ordinal


Mathematical operations can be performed on which of the scales of measurements?

Equalinterval


Name the three measures of central tendancy

average (mean), mode, median


The distance between each score.

Variance


Symmetry of the distribution of scores

Skew


The rate in which a curve rises and falls

Kurtosis


Most frequently obtained score

Mode


Center point of the scores when ordered from low to high  the point in a distribution above which at 50 percent of the test takers and below which are 50 percent of the test takes

Median


Arithmetic average

Mean


How the scores are spread out above and below the average score

Dispersion


What are the three measures of dispersion?

range, variance, and standard deviation


The distance between the two extremes scores of high and low (+1)

Range


Which two correlation coefficients have the best predictive value?

1.00; 1.00


True/False: Correlational data can't be used to draw a conclusion about causality.

True


(# correct/# possible) x 100

Percent correct
(Becca got 75% on her bio quiz) 

(# correct/# attempted) x 100

Accuracy


If George got a 96% on his english test, what level is he at?

Mastery


What are the three types of referenced interpretations of an individual's performance?

Criterion, Achievement Standards, Norm


Interpretations based on a similar group of people

NormReferenced


Interpretations based on a single fact

Criterion Referenced


Interpretations on a large scales to determine meeting a set of standards

Achievement StandardsReferenced


If Bill earned a percentile of 43% on a test, what does that mean in comparison to other test takers?

Bill did better than, or equal to, 43% of the test takers.


2.00; 1.00; 0; +1.00; +2.00
These are examples of what standard score? 
zscore


What standard score has a mean of 100?

IQ


IQ has a standard deviation of what?

15


A test was given a reliability coefficient of .98. Is it reliable?

Yes; 1.00 has smallest amount of error and 0.00 has large amount of error.


Ms. Dorner has only given multiple choice question tests this year. As a result, boys have been doing better in her class. What do we can this type of error?

Bias; Systematic; Predictable


What are the two approaches to generalizing for item reliability?

Alternateform; Internal consistency


How is alternateform defined?

two or more forms of same test; measure the same trait/skill; standardized on same population.


How is internal consistency defined?

After test is taken, questions are spilt and then correlated to see the reliability.


Mr. Fisk wants to check how stable are the test results for the Peabody Vocab test. How should he do this?

Test  Retest; See if test takers earn same scores at different times.


Extent to which the interpretation of the scores is supported by evidence and theory

Validity


What are the three most commonly categorized evidence of validity?

Content, Criterionrelated, Construct
(Remember it was CRITical to CONSTRUCT the TENT (content) 

Extent to which a person's score on a criterion measure can be estimated from that person's test score is what kind of validity?

Criterionrelated


Extent to which the test measures the theoretical construct it intends to measure is what types of validity?

Construct validity


Appropriateness of items, completeness of item sample and the way items are access leads to what kind of validity?

Content Validity
