Chapter 9 Flashcards
1
Q
Major Uses of Group Administered Tests
A
- Predicting success in future schooling
- Job selection/placement in business and military settings
- Research in the social or behavioral sciences
2
Q
8 Common Characteristics of Group Administered Tests
A
- Given to large groups
- Content similar to individual tests
- Multiple choice, machine scored
- Fixed time limit and number of items
- Bimodal distribution of administration times (45 to 60 minutes or 2.5 to 3.5 hours)
- Total score plus several subscores
- Normative samples are very large (200K to 400K)
- Principle purpose is prediction
3
Q
OLSAT8
A
- Created by Arthur Otis
- Otis-Lennon School Ability Test
- Measures verbal quantitative and figural reasoning skills most related to scholastic achievement
- Jointly normed with the Stanford Achievement Test
4
Q
OLSAT8 Structure
A
- 7 levels (A through G)
- School grade and age determine selection of level
- Time of about one hour
- Test levels overlap in their coverage to assess students who are of lower and greater ability within a level
5
Q
OLSAT8 Framework
A
- Adopts Vernon’s Hierarchical Model
- Specific factors > minor group factors > 2 major factors
- Measures the v:ed portion of the model
- Clusters of items including verbal comprehension, verbal reasoning, pictorial reasoning, figural reasoning, and quantitative reasoning
6
Q
OLSAT8 Scores
A
- Total score, verbal subscore, and nonverbal subscore
- All converted to School Ability Index (SAI)
- Mean = 100
- SD = 16
- Ages grouped from 5 to 19 separated into three month intervals
7
Q
Anticipated Achievement Comparisons (AACs)
A
OLSAT8 is used to predict performance on the Stanford Achievement Test
8
Q
OLSAT8 Norms
A
- Derived empirically for grades K-12
- Stratified by SES, geographical region, and ethnicity
- Fall and spring periods within each grade
9
Q
Two Cautions of OLSAT8 Norms
A
- Do not know percentage of students excluded from normative testing
- Know little about motivational level of students in the norming program
10
Q
Culture-Fair Tests
A
- Aim to create a test that is equally fair to individuals from different cultural backgrounds
- Example: Raven’s Progressive Matrices
- Good nonverbal measure of ‘g’
- Each item: pattern with a part missing, examinee selects the option that completes the pattern
11
Q
Culture-Fair Test Generalizations
A
- Not measuring general intelligence the same as other tests (mainly figural, spatial items)
- Predictive validity is less than verbal tests for school and job settings
- Still have group differences
12
Q
Six Generalizations of Group Administered Mental Ability Tests
A
- Same content as individual intelligence tests (vocabulary, reading, verbal relations, quantitative, and spatial)
- Reliability (total scores are very reliable, but sub-scores are less reliable)
- Predictive validity (0.3 to 0.6 range)
- Differential validity (generally poor because various combinations of subtests to not yield validity coefficients with higher than those obtained with total scores)
- Two special statistical issues (range restrictions and imperfect reliability in the criterion)
- Culture-free tests (elusive so far)
