psychometrics

Question 1

standardized

Answer 1

-rigorous development to establish consistent norms
-uniformity and consistency in the administration, session to session + evaluator to evaluator
- test has psychometric characteristics including reliability and validity

Question 2

psychometrics

Answer 2

-psychometric characteristics of a test has been studied and published
- these describe the “goodness” of a test
- includes the most common; reliability and validity

Question 3

reliability

Answer 3

• accuracy and stability of test
  1. test - retest - stability of test given on 2 occasions over time
  2. intra- rater rel. - same person gives test twice
  3. inter-rater-rel. - 2 people give the same test to same person

Question 4

validity

Answer 4

-what construct, traits, or behaviors the test measures
1. face validity- by appearance by experts logical judgement - makes sense
2. content validity- content represents the domain being measured (emotional measures)
3. criterion related validity- agreement between 2 tests

Question 5

norms

Answer 5

• test performance on standardized sample

Question 6

likert (scale type)

Answer 6

scale that has responses
ex. strongly agree, agree

Question 7

guttman (scale type)

Answer 7

increasing strength of response until they no longer agree

Question 8

checklist (scale type)

Answer 8

check those that … or multiple choice answers

Question 9

forced choice

Answer 9

likert with even #

Question 10

Q sort

Answer 10

stack of items sorted

Question 11

item analysis

Answer 11

• does each item make sense, belong in the test, measure something different, does it consistently measure between similar groups

Question 17

why use non standardized

Answer 17

• allow flexibility
• easy to administer, little time
• cheap
• long scoring not required

Question 18

p-value

Answer 18

probability of what you found being true (type 1 or 2 error)
*smaller the p-value = stronger evidence against null hypothesis (LOW P-VALUE = GOOD)

Question 19

correlation

Answer 19

-relationship between 2 variables (r)
- want r to be high & p-value to be low
