WEEK 6 REFLECTION

Question 1

Standardized Test

Answer 1

Yield norm ref or criterion ref inferences
predetermined
testing firms
norm ref interpretations = goal
student aptitude/achievement measurement

Question 2

Norm-Referenced

Answer 2

Interpret student performance in relation to others
Taken same assessment
Look at individual scores compared to others/relate

Question 3

Criterion-Referenced

Answer 3

Interpretation
Test mastered by student
Assessed based on curricular aim mastery

Question 4

Mean

Answer 4

arithmetic average of a set of scores
useful for variability
helps when scores are centered

Question 5

Median

Answer 5

midpoint of set of scores
useful for variability
helps when scores are centered

Question 6

Stanine

Answer 6

Final kind of scale score
Assume normal distribution for score set
More gross score
Score distribution into 9 segments
5th is at the center

Question 7

Percentile

Answer 7

Aka percentile ranks
frequency describing standardized test scores
Readily understandable
Compares score with norm group

Question 8

Normal Curve Equivalent

Answer 8

Scale score
NCE
Use raw score to for arrive at percentile raw score if test turns out as bell shaped curve

Question 9

Standard Deviation

Answer 9

Average
Difference in individual scores in group/mean of those scores
Larger= more spread out scores in distribution

Question 10

Standard Error of Measurement

Answer 10

SEM
reliability/precision procedure
reflection of consistency of scores if given multiple times
higher test reliability = smaller SEM

Question 11

P-Value

Answer 11

Commonly employed item difficulty index
p = r over t
r = number of students responding correctly
t= total of students responding to item
range from 0 -1.00
higher value = more correct responses
view in relationship of probability answering correctly

Question 12

Scaled Score

Answer 12

Average of group of numbers scaled
Useful for comparing performance over time and grades
Transforms raw test into measurable units
Weighted

Question 13

Item Response Theory

Answer 13

IRT
Scale score report sytem
Take difficulty into consideration/technical properties of test items
Each grade has different avg scale score
Help devise vertical scale

Question 14

Grade Equivalent

Answer 14

Student test performance
grade level progress in school
months of school year
transform scores on standardized test to index
Developmental and shows cont. range of students

Question 15

Item Discrimination

Answer 15

Determine how well an item is able to discriminate between two levels of students
Important in norm referenced testing/interpretation
