What a finished MATH 225 Week 3 descriptive statistics write-up looks like
Short, and more prose than a problem set. One variable is chosen and stated with its measurement unit before any figure appears. Center and spread are reported together rather than in separate paragraphs, because neither means much alone. A picture of the distribution sits in the document with axes labeled and a caption saying what it shows, not a bare image dropped in mid-page. Shape is then described in words a nurse would use: bunched at the low end, a long tail to the right, a few values sitting well away from the rest. The final paragraph reads the whole thing back as a statement about patients, and it states plainly that no comparison has been made and no other group is being described.
How a MATH 225 Week 3 example is structured
Section templates differ and some classrooms supply the data set while others let a public one be chosen. The write-up opens on the variable and where the values came from, in two or three lines, since a distribution with no stated origin cannot be interpreted at all. Descriptive figures follow in a fixed order, center before spread, each labeled with its unit and rounded once. The graphic comes after those figures rather than before them, so a reader arrives at the picture already knowing what to look for in it, and its caption carries a number and a short title. Shape is described next, including any values sitting far from the rest and what a nurse would suspect had produced them. The final paragraph converts everything into ordinary language and marks the boundary of the document.
The variable, before the numbers
What is being measured, in which unit, and where the values came from, since a distribution with no stated origin cannot be read in clinical terms.
Center and spread together
Both reported in one place and rounded once, because a typical value means little until the reader knows how widely the group scatters around it.
A graphic that carries a caption
Axes labeled with units, a numbered caption and a short title, so the picture states its own subject without the surrounding paragraph having to.
Shape in ordinary words
Bunched, tailed or symmetric, described the way a nurse would describe it, with any far-off values named and a plausible reason for them offered.
Read back, and bounded
A closing paragraph saying what this distribution means for these patients, ending on the limit of what a description alone is entitled to claim.
Where marks go in MATH 225 Week 3
The dearest loss is the figure dump, a page of statistics with no paragraph reading them, which the rubric treats as an unfinished document rather than a wrong one. Next is the unlabeled graphic: axes without units, no caption, no number, dropped into the middle of the text. Third is a mean reported for a distribution the writer has just called strongly skewed, with no median beside it, which tells the instructor the shape was described but never believed. Fourth is the outlier noticed and left, mentioned once and never explained or handled. Last is a conclusion that starts predicting, reaching toward patients who are not in the set, which belongs to a later week and costs points when it turns up in this one.

MATH 225 Week 3 questions, answered
Which does the rubric want, the mean or the median?
Whichever the shape supports, and the marks come from saying why. Where values are roughly symmetric the mean stands alone comfortably. Where a long tail pulls it, the finished example reports both and says in a clause that the median describes a typical patient better here. Choosing one and defending the choice earns more than reporting every measure available and ranking none of them.
Does a chart have to be included?
Nearly every section wants one, and the format is usually left open. What the rubric penalizes is not the choice of chart but a chart that fails to identify itself. The example labels both axes with units, numbers the figure, gives it a title and refers to it by that number in the text, so a reader never has to infer what is shown.
How is this different from the later testing weeks?
Description stops at the data in hand. Nothing in this write-up claims anything about patients who are not in the set, and the final line says as much. Later weeks add the machinery for reaching past a sample, and the interpretation sentences change accordingly. Writing a Week 3 conclusion that already generalizes is the most common way this particular document loses points.
