What a finished NU 600 Unit 7 examination item analysis looks like
The finished analysis is a small report with numbers in it and an argument around them. It states the test, the group and the conditions, then presents each item with the proportion answering correctly and a discrimination figure, and it explains what those two numbers mean together rather than assuming a reader knows. Distractor performance is examined for the items that misbehaved, since an option nobody selects is doing no work and an option chosen by the strongest learners usually signals two defensible answers. Items are then sorted into keep, revise and remove, each with a reason drawn from the data and from the content. The report closes with what the pattern says about the teaching, not only about the test.
How a NU 600 Unit 7 example is structured
The report moves from the whole test to the single item and then back out to the teaching. It opens with the context, because a difficulty figure means one thing after a first attempt and something else after review sessions. Whole-test figures come next and are kept short. Item-level data then runs in a fixed table so difficulty and discrimination can be read together, which is the only way either number is informative. The items that misbehaved are pulled out for individual treatment with their distractors examined and their wording quoted. Decisions follow in three categories with reasons attached, and any change to the scoring is stated plainly along with what it does to the group's results. The closing section reads the pattern back onto the instruction, since items everybody missed often indicate a session rather than a question.
Difficulty and discrimination read together
Neither figure means much alone, so the report interprets them as a pair and says what an easy item with negative discrimination indicates.
Distractors examined, not just totals
Options nobody selected and options chosen by the strongest learners are inspected, because that is where a defective item usually explains itself.
Decisions sorted into keep, revise, remove
Each item is assigned an outcome with a reason from the data and the content, rather than being described and then left where it was.
Scoring consequences stated plainly
If an item is dropped the report says what that does to the results, since a change made quietly becomes a fairness problem later.
The pattern read back onto teaching
Items the whole group missed are treated as evidence about a session, which is what turns a test report into an instructional finding.
Where marks go in NU 600 Unit 7
Item analyses stall at arithmetic presented as interpretation. A table of difficulty indices with nothing said about them answers none of the questions the criterion asks, because the numbers were never the point. Reading difficulty alone is the second loss, since an item everybody answers correctly may be an appropriate check of something essential, and the discrimination figure is what tells those apart. Papers that condemn every hard item confuse difficulty with defect. Ignoring the distractors leaves the diagnosis unfinished, given that a flawed item is usually visible in which wrong option attracted whom. Recommending changes without saying what happens to scores already awarded avoids the awkward part. The largest missed opportunity is a report that never asks what the failed items say about the teaching.

NU 600 Unit 7 questions, answered
Where do the item numbers come from if I have no test data?
Many sections supply a data set, and where none is given a clearly labeled illustrative set works, provided the figures behave the way real ones do. Build in a couple of items that misbehave, since a fabricated table where everything performs well gives you nothing to examine. Never present invented figures as results from a real classroom, and say in the paper where your data came from.
How small a group can be analyzed this way?
Small groups produce unstable figures, and the honest version of the report says so. With twenty learners a discrimination index moves considerably on one changed answer, so treat the numbers as a prompt for inspecting the item rather than as a verdict on it. Say what the group size does to your confidence, because a reader who knows the statistics will look for that sentence.
Should the analysis recommend rewriting items?
Where the instructions ask for it, yes, and a proposed revision is usually more convincing than a criticism. Quote the original stem and options, name the flaw precisely, whether it is a clued answer, an implausible distractor or two defensible keys, and show the rewritten version beside it. What to avoid is a general recommendation to improve question quality, which points at nothing.
