1. performance on item related to estimated amount latent trait being measured (can compare scores of people tested w/ different items)
2. invariance of item parameters (results of testing sample free) 3. can compare total test scores of sample to proportion who answered each item correctly |
|
p level
|
item difficulty
% got item right |
|
avg difficulty level for t/f test
|
.75 -- halfway b/w success w/ chance and everyone getting right
|
|
scale of p level
|
ordinal
|
|
D
|
item discrimination
= (% got right upper score group) - (% got right lower score group) 100 = max |
|
relationship item discrimination and item difficulty
|
item difficulty level (p) places upper limit on item discrimination (D)
p = .5, then max D |
|
relationship D and test reliability
|
higher mean D, higher reliability
|
|
other ways calculate item discrimintation
|
correlate w/ total test and retain high correlation items (if measure 1 trait)
correlate w/ external criterion |
