This page holds a finished MATH 225 Week 7 regression write-up, showing the scatterplot, the fitted line, the strength of the relationship and a strictly non-causal reading. Searches like "math 225 week 7 assignment example", "math225 week 7 sample" and "math 225 week 7 example" land here.
What a finished MATH 225 Week 7 regression write-up looks like
The scatterplot comes early and it is a real figure: both axes labeled with units, the explanatory variable on the horizontal, a caption, and the fitted line drawn on it rather than described in the text. The two variables are identified by which one is being used to explain the other, and the document says why that direction was chosen instead of the reverse. The equation is reported with its slope read in units, so many units of the outcome for each unit of the other, rather than as a bare coefficient. Strength is reported separately from direction. The interpretation paragraph is written in verbs of association throughout, and it names at least one third factor that could sit behind both variables.
How a MATH 225 Week 7 example is structured
Data sources differ by section and some classrooms supply the pairs while others allow a public set. The document begins with the two variables and the question connecting them, a sentence each. The direction of the fit is justified next, briefly, because deciding which variable explains which is a clinical judgment and not a formatting default. The scatterplot follows with its line drawn in and its caption numbered. The fitted equation is then given, its slope translated into units a reader recognizes, and its strength reported as a separate figure with a plain word attached: weak, moderate, strong. Any prediction the item asks for is made only inside the range of the observed values, and the document says that is the reason. The closing paragraph reads the association clinically and names what else could explain it.
Which variable explains which
The direction of the fit stated and justified in a line, since it is a decision about the clinical question rather than a formatting default.
A scatterplot with the line on it
Axes labeled with units, the fitted line drawn rather than described, and a numbered caption, so that the figure makes its argument on its own.
The slope, translated
The coefficient read back in units of the outcome for each unit of the other variable, which turns a number into something a nurse can picture.
Strength apart from direction
The strength of the relationship given as its own figure with a plain word attached, kept separate from whether that relationship runs up or down.
Association verbs only
The reading paragraph written throughout in the language of association, naming at least one other factor that could be sitting behind both variables.
Where marks go in MATH 225 Week 7
The costliest failure here is a single verb. A write-up saying that one variable raises, drives, reduces or improves another has made a causal claim from a correlation, and instructors take it seriously because the distinction is the entire point of the week. Next is a slope reported as a number with no units, which leaves the sentence around it unreadable clinically. Third is prediction beyond the data, extending the line to values nobody observed and then quoting the result. Fourth is strength and direction conflated, a negative relationship called weak because the figure carries a minus sign. Last is a scatterplot with unlabeled axes, or with no caption, which is the easiest set of points on the page to keep and one of the most commonly dropped.

MATH 225 Week 7 questions, answered
Which verbs are safe in the interpretation?
Ones describing movement together rather than production. Associated with, tends to accompany, rises alongside, is related to. The verbs that cost points are the ones smuggling in cause: causes, drives, raises, lowers, improves, prevents. Instructors read this paragraph closely, because a correct fit followed by a causal sentence is the defining error of the topic and it is entirely a wording problem.
Can the fitted line be used to predict?
Inside the range of the observed values, yes, and most items ask for exactly that. Outside it, no, and saying why earns more than the prediction itself. Nothing in the data supports the relationship holding at values nobody measured, so the example makes its prediction within range and adds a sentence declining to extend the line past it.
How much does the scatterplot matter to the grade?
More than most submissions assume. The figure is usually a named rubric item, and it is where an unlabeled axis, a missing caption or a line described in text but never drawn costs easy points. It also does argumentative work: a reader who can see the scatter is able to judge whether the fitted line is a fair summary of it.
