EPPP

Question 1

What is negative predictive value

Answer 1

A test says the person does not have a disease and they actually do not have a disease

Question 2

What is positive predictive value

Answer 2

A test says the person has a disease and they actually do have the disease

Question 3

What is specificity

Answer 3

The probability that a test will correctly identify people without the disease from the pool of people without the disease

Question 4

What is sensitivity

Answer 4

The probability that a test will correctly identify people with the disease from the pool of people with the disease

Question 5

Are Z scores a standard score yes or no

Answer 5

Yes

Question 6

Are T scores standard score yes or no

Answer 6

Yes

Question 7

Is a percentage score a standard score yes or no

Answer 7

No

Question 8

Is a Wechsler IQ score a standard score yes or no

Answer 8

Yes

Question 9

The item difficulty index ranges from

Answer 9

0-1.0

Question 10

Item difficulty - 0 =

Answer 10

No one answers the item correctly

Question 11

Item difficulty - 1.0 =

Answer 11

Everyone answers the item correctly

Question 12

If a test developer wants to add more difficult items to her test, she will include items that I have an item difficulty index of? .90, .10, .50 or 0

Answer 12

.10; not 0- it’s not useful to have items that nobody can answer

Question 13

Divergent validity

Answer 13

Scores on a measure do not correlate with scores on measures of unrelated traits

Question 14

Item response theory

Answer 14

Scores are reported in terms of the examinees level on a trait or ability measured by the test instead of in terms of a total score

Question 15

What kind of validity Does a measure have when it correlates highly with other measures of the same trait

Answer 15

Convergent validity

Question 16

Attest has divergent or discriminant validity when

Answer 16

When a measure has a little correlation with measures of different traits

Question 17

The multitrait multi method matrix contains correlation coefficients that provide information about

Answer 17

Convergent and discriminant validity

Question 18

Kappa statistic provides a more accurate estimate of reliability than percent agreement as far as interrater because

Answer 18

It’s calculation includes removing the effects of chance agreement

Question 19

Which type of reliability is most appropriate for estimating the reliability of a multiple choice speed test

Answer 19

Alternate forms reliability

Question 20

A coefficient of stability is obtained by

Answer 20

Administering the same test twice to the same group of people on two different occasions and then correlate the two sets of scores

Question 21

Consensual observer drift occurs when observers ratings become

Answer 21

Increasingly less accurate overtime in a systematic way

Question 22

What’s the best way to control consensual observer drift

Answer 22

Alternate raters. This occurs when the Raiders were working together influence each other‘s rating so that they assigned readings and increasingly similar ways

Question 23

The reliability coefficient just like any other correlation coefficient is larger when

Answer 23

There is an unrestricted range of scores, so when the tryout sample contains examinees were heterogenous with regard to the attribute measured by the test. Homogenous sample would restrict the score range thereby impacting reliability.

Question 24

The very best way to demonstrate that it has has adequate reliability is by using what method that is fairly costly time consuming and difficult

Answer 24

Alternate forms or equivalent forms

Question 25

In the factor analysis when 2 factors are orthogonal this means that

Answer 25

They are not correlated

Question 26

The monotrait heteromethod coefficient is a measure of what kind of validity

Answer 26

Convergent

Question 27

Heterotrait monomethod coefficient is a measure of

Answer 27

Divergent validity

Question 28

Monotrait and monomethod coefficient indicates

Answer 28

Reliability

Question 29

Heterotrait-heteromethod is a measure of

Answer 29

Divergent validity

Question 30

Cronbachs alpha is an appropriate method for evaluating reliability when

Answer 30

All test items are designed to measure the same underlying characteristic

Question 31

Cronbachs alpha is another name for

Answer 31

Coefficient alpha and it’s used to assess internal consistency reliability

Question 32

Incremental validity is a measure of

Answer 32

Decision making accuracy. It refers to the increase or increment in decision-making accuracy that results from the use of a new predictor for example the increase in accurate hiring decisions

Question 33

Attest developer would use the Kuder Richardson formula KR20 in order to

Answer 33

Evaluate a tests internal consistency reliability

Question 34

The optimal item difficulty level for a true false test is

Answer 34

.75 which is half way between 100%. .75 is half way between 100% and 50%

Question 35

According to classical test theory total variability in test scores is due to

Answer 35

True score variability plus random error

Question 36

Which formula estimates the effects of shortening or lengthening a test on the test reliability coefficient

Answer 36

Spearman Brown

Question 37

Cross validation refers to

Answer 37

Reassessing a tests criterion related validity with a new sample
