For AC312 Unit 4, the descriptive analysis exercise reports counts, sums, a skewed mean and vendor concentration, each labeled with the rows it covers. Searches like "ac 312 unit 4 assignment example", "ac312 unit 4 sample" and "ac312 unit 4 example" land here.
What a finished AC312 Unit 4 descriptive analysis exercise looks like
A summary table, two short distribution panels and a page of definitions. The table reports 41,512 cleaned rows, split into 39,566 payments totaling 64,227,030.40 and 1,946 credit memos totaling negative 1,232,329.15. For payments alone it gives the mean of 1,623.29, the median of 612.40, a standard deviation of 4,905.18 and a maximum of 186,400.00, a single installment on new yard racking. The first panel shows payments by size band, with most rows under 1,000 and most dollars above 10,000. The second shows concentration: twenty vendors take 58.6 percent of payment dollars, while 214 of the 1,137 vendors were paid once. The definitions page states, for every figure, whether credit memos, flagged vendors and rows without purchase orders were included.
How a AC312 Unit 4 example is structured
Counts come before amounts, and totals before averages, because each later figure depends on the population an earlier one fixed. The summary table therefore opens with rows and the split between payments and credit memos, since averaging the two together would describe no real transaction. Central tendency follows, and the gap between mean and median is explained in a sentence: a few very large payments pull the mean upward, so the median better describes a typical invoice. The size-band panel shows the same skew in counts and in dollars. The concentration panel turns to vendors, which is where the accounting consequence lives, since a handful of relationships carry most of the exposure. The definitions page closes the exercise, and each figure in the table carries a superscript pointing to its entry there.
Rows before dollars
41,512 cleaned rows, split into 39,566 payments and 1,946 credit memos. The split comes first because every later statistic depends on which side it uses.
A mean pulled upward
Mean payment 1,623.29, median 612.40, standard deviation 4,905.18. A handful of large installments explains the gap, and the median is named the better description of a typical invoice.
Size bands in rows and in dollars
Most payments fall below 1,000, while most dollars sit in payments over 10,000. Both views appear together because each hides what the other shows.
Twenty vendors, most of the money
Twenty of 1,137 vendors receive 58.6 percent of payment dollars. The exercise notes that confirmation and cutoff testing would concentrate there.
What each figure counted
A definitions page states, figure by figure, whether credit memos, flagged vendors and rows lacking purchase orders were in or out.
Where marks go in AC312 Unit 4
Averages computed across payments and credit memos together lose the most, since the result describes neither and understates the typical payment. Graders then look for the definitions: a figure with no statement of what it counted, such as a vendor total that silently includes one-time vendors, cannot be checked and loses method points. Reporting the mean alone, when the data are this skewed, costs interpretation marks, and so does noticing the skew without explaining it. Percentages without a stated base draw deductions in most sections. The concentration finding earns little if it stops at the percentage without saying what it implies for the accounts, such as where confirmation or cutoff work would matter most. Tables whose totals do not reconcile to the cleaned population lose arithmetic points.

AC312 Unit 4 questions, answered
Why report the median when the mean is already there?
Because payment data are almost always skewed. A few large invoices, equipment installments or rent, pull the mean far above what a typical payment looks like, and a reader relying on it would misjudge the normal scale of activity. Reporting both, with a sentence explaining the gap, is standard in AC312 descriptive work and often earns an interpretation mark of its own.
Should credit memos be excluded from the analysis?
Not from the population, only from statistics where they distort the meaning. The totals include them, because the net figure is what ties to the ledger. Averages and size bands exclude them, because a negative credit memo averaged with payments describes no real transaction. The AC312 sample states which applies to every figure on its definitions page.
How much interpretation does a descriptive exercise need?
More than the name suggests. Each figure is expected to come with a sentence saying what it shows about the accounts, even at this early stage. Concentration among twenty vendors, for instance, tells an accountant where confirmation and cutoff work would be most useful. Descriptive tables with no sentences attached tend to score in the lower half of most AC312 rubrics.
