Beneath each crosstab table, this ninth-week interpretation places a sentence: which percentages answer the question, what the chi-square and Cramer's V say, which cells drive it, and where counts run thin.

What a finished DDBA 8307B Week 9 SPSS output interpretation looks like
Two to three pages with three SPSS tables as exhibits: the Crosstabulation, Chi-Square Tests and Symmetric Measures. Under the crosstab, the first sentence states which percentages answer the question, the share of each account type that reordered, read within rows, and gives them in plain words. The chi-square sentence follows in standard form, with degrees of freedom and significance, and the footnote on expected counts is reported and interpreted, since Cochran's guidance on small expected frequencies decides whether the test can be trusted here. Cramer's V appears next with a sentence on strength. Adjusted residuals in the crosstab cells show that retail shops reorder less often than independence would predict, and the interpretation names that cell as the source of the association. A closing paragraph states what a sales manager can take from the tables and what they leave unsettled.
How a DDBA 8307B Week 9 example is structured
Each exhibit is followed immediately by the sentences that read it, so no table stands alone. The crosstab comes first because it holds the finding; the tests come after because they only say whether the pattern in the crosstab is larger than chance would produce. Percentages are chosen to match the question, and the interpretation says which direction it reads, since column percentages answer a different question and many drafts report the wrong one. The chi-square paragraph reports the test and the expected-count check together, and the strength paragraph turns Cramer's V into ordinary language. The residuals paragraph localizes the association to specific cells. A short limits paragraph notes that reordering within sixty days is a narrow measure of account health and that one season's counts describe that season.
Which percentage answers
The question is whether account types differ in reordering, so percentages are read within account type. The interpretation says so, because reading down the columns instead would answer what share of reorders came from each type.
The test, with its footnote
Chi-square, degrees of freedom and significance appear in one sentence, followed by the footnote on cells with small expected counts. Reporting the footnote shows the author checked whether the test's approximation holds.
Strength in words
Cramer's V is stated and translated: the association between account type and reordering is modest, so account type explains part of the reordering picture and leaves most of it to other factors.
The cells that carry it
Adjusted residuals show retail shops reordering less than independence predicts, with bars and restaurants close to expectation. The finding is named as a retail pattern, not a general difference.
What sixty days measures
Reordering within sixty days is one window on account health. Shops with longer shelf cycles may reorder later without being less loyal, and the interpretation says the table cannot tell those apart.
Where marks go in DDBA 8307B Week 9
Output interpretation is marked sentence by sentence against the tables. A write-up quoting the chi-square value and significance, and nothing else, has reported a test without saying what pattern it tested, and it lands low. The percentage sentence carries heavy weight, because reading the wrong direction answers a different question while looking correct. Graders check the expected-count footnote: ignoring it, or failing to say what it means for trust in the test, draws comment in most sections. Effect size is expected, and a significant chi-square described as a strong relationship without reference to Cramer's V overstates it. The residuals paragraph earns doctoral credit by locating the association precisely. The limits paragraph is scored on specificity about the measure, and a closing claim about retail accounts being less loyal outruns the table.

DDBA 8307B Week 9 questions, answered
What if the expected-count footnote reports too many small cells?
Then the chi-square approximation is doubtful, and the interpretation says so before reporting the result. Common remedies include combining sparse categories where that makes substantive sense, or using Fisher's exact test for small two-by-two tables. Whichever route is taken, the write-up explains the choice and how it changed the question, since merging categories alters what the comparison means.
Should row or column percentages be reported?
Whichever matches the question. If the question is whether account types differ in reordering, percentages within account type answer it. If the question is what share of reorders came from each type, the other direction does. Strong interpretations state the question first, choose the direction to fit, and mention the alternative only if a reader might reasonably expect it.
Is Cramer's V always needed?
In most doctoral sections, yes, or phi for two-by-two tables. The chi-square test says whether an association is distinguishable from none; it says nothing about how strong it is. Reporting V with a plain-language reading of its size gives the reader the second half of the answer. Without it, a significant result tends to be read as more important than it is.
