| Calculating a PIP
| Helps you decide which test to develop first.
From Engineering Human Performance by Tom Gilbert.
< |
| JTA Gantt Chart
| Template for all tasks required to administer and
analyze a Job Task Analysis. Provides both a Gantt
Chart and a List of Tasks by Date.
< |
| 2 x 2 Analysis
| Conceptual experimentation spreadsheet. Lets you compare
validity measures using Chi Squared, Tetrachoric R, Kappa,
and the Agreement Coefficient.
< |
| Item Analysis Worksheet
| Given exam score data, calculates the point-biserial
point-biserial correlation and P-Values for all items.
< |
| Item Filter
| Evaluates whether items meet psychometric constraints
for point-biserial correlation and P-Value bounds.
|
| Adaptive Scale Correlations
| Enables small-sample adaptive testing with independent scales.
Computes scale intercorrelations for adaptive administration.
Also prioritizes sequence of scale administrations.
|
| Cutpoint Computation
| Computes the appropriate cutscore for your exam
using Angoff, Bookmark, or Contrasting Groups methods.
|
| Scale Consistency Classification
| Computes Kappa, a measure of agreement, for ratings
of up to 5 raters on 6 scales for up to 100 items.
|
| ScaleMark
| Computes an appropriate cutscore for multiple
scales in an exam using ScaleMark procedure.
|
| Time & Accuracy Scoring
| Uses both time and accuracy to compute a
performance efficiency integrated matrix.
|
| Trial Item Pool Size
| Computes the optimal trial item pool size
to include in the next release of a test.
|
| Inter-Rater Reliability
| Measures inter-rater reliability for three
raters, using a Kappa computation.
|
| Scale Stability Index
| Measures reliability for scales in a test
using a stability measure, as opposed to
an internal consistency measure.
|
| Bias Calcs
| Computes bias calculations to see if a test
conforms to EEOC guidelines.
|
| Scaled Score Converter
| Converts a raw score into a scaled score by either
of two methods: Linear rescaling or bilinear rescaling.
Includes a graphic of the linear rescaling model.
