What a finished BU 351 Unit 3 descriptive analysis looks like
A definitions page comes first, and it is shorter than it sounds but does most of the work. Each measure is written out as a formula in words: which records count toward it, which are excluded, what the denominator is, and what period it covers. The results follow as a small number of tables and charts, each answering one of the framed questions from earlier in the term rather than displaying everything the file contains. Every figure sits beside a comparison, whether that is the same measure a period earlier, another segment, or a stated target, since a number alone carries no information. Distributions appear where an average would mislead. A closing passage states plainly what the summary does not establish, listing the explanations a reader might reach for and why none of them follow from this evidence.
How a BU 351 Unit 3 example is structured
Measures are defined before any of them is computed because two people counting active customers will get different totals from the same file, and an analysis whose definitions are implicit cannot be reproduced. The aggregation level is stated once and held, since a table mixing record level rows with monthly summaries is the commonest way these documents become unreadable. Comparisons are attached to every figure rather than provided in a separate section, as the comparison is what converts a number into a finding. Distributions are shown wherever the shape matters, because a mean over a skewed measure describes nobody in the file. Charts are chosen to answer the question rather than to fill the page, and each carries the definition it was built from. The refusal to explain closes the document, and stating it explicitly is what keeps the next unit from being spent early.
Every measure defined before computation
Inclusions, exclusions, denominator and period are written out for each measure, since two readers counting the same thing otherwise disagree.
One aggregation level held throughout
The document fixes what a row represents and stays there, because mixing record level detail with period summaries makes a table unreadable.
Comparison attached to every figure
Each number appears beside an earlier period, another segment or a target, as a lone figure gives a reader nothing to judge.
Distributions shown where averages mislead
Where a measure is skewed, the shape is reported rather than a mean that describes nobody actually present in the file.
The explanation deliberately withheld
A closing passage names the causes a reader might assume and says why this evidence cannot support any of them.
Where marks go in BU 351 Unit 3
Descriptive work loses credit by explaining. A sentence attributing a rise to a campaign, a season or a price change has left the type of analysis this unit is about and asserted something the data cannot show. Measures used without definitions leave a marker unable to reproduce a single total. Documents dumping every chart the tool would produce force the reader to find the answer. Averages reported over skewed measures describe a customer who does not exist. Figures given with no comparison are trivia. Charts whose axes start partway up exaggerate movement, and a marker checking one will treat it as a presentation defect. Percentages quoted without their denominator cannot be checked. Database extracts and customer tables from an employer's systems are not permissible material here.

BU 351 Unit 3 questions, answered
Is it really wrong to suggest a reason for a change?
It costs marks in this unit specifically, because the criterion is testing whether you know what a summary can support. Where you spot something that looks like a cause, record it as a question for the next stage rather than as a finding. That reads as discipline instead of omission, and it hands you material for the exploratory work that follows.
How many charts belong in the document?
Fewer than the tool will offer. Three or four that each answer a framed question beat a dozen produced because the software made them easy, and the extra ones dilute the marks rather than adding to them. Where a table would be clearer than a chart, use the table. Every visual should have a sentence saying what the reader is meant to take from it.
Which comparison should the figures be set against?
Whichever one the framed question implied, and say why you chose it. A prior period suits a measure expected to move over time; another segment suits a question about difference; a target suits anything with a stated goal behind it. Where the case gives you none of these, build the comparison from the file itself and label it as constructed rather than external.
