Two goaltenders, one tempting gap and the two traps a seminar group found in it: why .921 against .908 decides nothing, argued in a seminar reflection for MT241 Unit 6. Searches like "mt 241 unit 6 assignment example", "mt241 unit 6 sample" and "mt241 unit 6 example" land here.
What a finished MT241 Unit 6 seminar reflection looks like
Two first-person pages with a small table, drawing on the course text and on a public analytics site's explanation of goals saved above expected. The table sets out the file the seminar read: the starter at .908 on 1,655 shots, the backup at .921 on 494. Two rows added during the session change the reading. A 95 percent interval around each figure runs from about .894 to .922 for the starter and .897 to .945 for the backup, overlapping across most of their width. Shot quality differs as well: the backup faced 0.071 expected goals per shot, the starter 0.083, largely because the backup's starts fell on second nights of back-to-backs against weaker opponents. Measured against expected goals, the two differ by about one goal per thousand shots.
How a MT241 Unit 6 example is structured
The writer's claim, rather than the session's chronology, organizes the reflection. It opens with the argument as it stood before the seminar, set out fairly: a higher save percentage over nearly a quarter of the season's shots. The dataset comes next, as the group read it. Two traps then get a paragraph each, in the order the group found them. The first is sample size: a binomial interval around each save percentage, computed in the session, shows the backup's figure could sit anywhere across a range wide enough to contain the starter's. The second is shot quality, which the writer had not considered: the backup faced easier shots on average, so part of his higher save percentage was expected. Goals saved above expected closes the gap. The last third states the revised position, keep the starter and review later, and names the evidence that would reopen the question.
The case as first argued
A .921 against a .908, over nearly 500 shots, looked decisive to the writer before the session. The reflection states that argument at full strength so the later revision can be judged against it.
An interval around each number
The group computed a 95 percent binomial interval for each goaltender. The two ranges, .894 to .922 and .897 to .945, overlap across most of their width, so the file cannot say which one stops pucks better.
Easier shots on quieter nights
The backup started mostly on the second night of back-to-backs, against weaker opponents, and faced 0.071 expected goals per shot to the starter's 0.083. Part of his higher save percentage belonged to the shots, not the saves.
One goal per thousand shots
Against expected goals, the starter allowed about 15 more than his shots predicted and the backup about 4 more. Per shot, the two differ by roughly one goal per thousand, a margin no lineup decision can rest on.
Keep the starter, set a date
The revised position keeps the starter and reviews after 25 more backup starts, using goals saved above expected. A gap of five goals or more by then would reopen the argument, and the reflection explains that threshold.
Where marks go in MT241 Unit 6
Reflections that summarize who spoke in the session, with no trace of what the writer thought before or after, miss what the Unit 6 seminar in MT241 is built to produce. The dataset belongs on the page, since the session read it together and a reflection that never shows the numbers cannot show the traps in them. Accuracy counts even in first person: an interval computed wrongly, or expected goals described as a count of shots, costs credit a careful sentence would have kept. Drafts that swap one confident verdict for another, backup to starter, repeat the error in reverse. A revised position without a condition that would change it again reads as persuasion, not reflection. If the written alternative stands in for attendance, the assigned dataset replaces the group, and the traps must still be found.

MT241 Unit 6 questions, answered
How big a sample does a goaltender's save percentage need?
Larger than one season usually provides. Save percentages cluster tightly across the league, so the differences that matter are small, and random variation over a few hundred shots exceeds the gaps between most goaltenders. An interval, even a rough binomial one, shows how much of a difference could be noise. The example's intervals overlap almost completely.
What is goals saved above expected?
The difference between the goals a goaltender would be expected to allow, given the quality of the shots faced as scored by an expected-goals model, and the goals actually allowed. A positive figure means he stopped more than the shots predicted. It adjusts for shot quality, which raw save percentage ignores, though it inherits the model's blind spots, such as screens and pre-shot passes.
Can a reflection end without a firm recommendation?
It can end with a firm position about the evidence instead of a verdict on the players. The example keeps the starter because the data does not justify a change, then sets a date and a threshold for revisiting. That is a decision with its conditions stated, and it usually earns more than a confident choice the numbers cannot support.
