Translating an SPSS t test table into blood pressure terms, the PU525 Unit 6 output interpretation memo example tells a program director what a 5.8 mmHg difference means. Searches like "pu 525 unit 6 assignment example", "pu525 unit 6 sample" and "pu525 unit 6 example" land here.
What a finished PU525 Unit 6 output interpretation memo looks like
Addressed to the director of a composite county health department's hypertension program, the memo fills two pages, with the output attached. Up top, the finding appears in plain terms: participants averaged 132.4 mmHg at follow-up against 138.2 among comparison residents, a difference of 5.8 with a plausible range of 2.6 to 9.0. The memo then walks through the output in the order SPSS prints it. Group Statistics supplies the sample sizes, 186 and 190, with means and standard deviations. Levene's test, at a significance of .31, supports the equal-variances row. The t of 3.58 on 374 degrees of freedom appears with its p value, which SPSS prints as .000 and the memo reports as below .001. The memo ends on why a non-randomized comparison limits what the director can claim publicly.
How a PU525 Unit 6 example is structured
The memo reverses the software's order at first and then follows it. The finding leads, because the director asked whether the program lowered blood pressure and should not have to read a table to learn the answer. The walkthrough then follows the output block by block, so a reader holding the attachment can find each number where the memo discusses it. Every statistic that carries a unit is stated in it: the difference, the standard error of the difference and the confidence limits are all in mmHg, while the t statistic and p value are explained as unitless measures of how surprising the gap would be under no effect. The practical meaning of 5.8 mmHg comes after the statistics, and the design caveat follows last, since a program that chose its own participants cannot separate its effect from who enrolled.
The answer in the units measured
Two means, the difference and its 95 percent interval, all in mmHg, in the memo's first three sentences. Nothing statistical is named before the reader knows what changed.
Group Statistics block
Sample sizes, means, standard deviations and standard errors for each group. The memo notes that standard deviations near 15 and 16 mmHg show wide individual variation behind the averages.
Levene's row and why it matters
Levene's test decides which line of the t test output to read. With a significance of .31, the equal-variances row applies, and the memo says so in one sentence instead of skipping the choice.
What .000 does not mean
SPSS rounds tiny p values to three zeros. The memo reports p below .001 and explains that a probability is never exactly zero, a correction graders in many sections look for.
Who enrolled
Participants volunteered, and the comparison residents lived in neighboring areas. The memo recommends describing the result as an association and names baseline pressure as a variable the next evaluation should adjust for.
Where marks go in PU525 Unit 6
Output memos tend to be graded on accurate reading of the output, interpretation in context, and communication to the named reader. Reading marks require the right row, the right tail and the right numbers: the equal-variances line chosen for a stated reason, a two-tailed p value reported as such, and a confidence interval copied with its sign understood. Interpretation marks go to statements in the outcome's units; a memo that says the result was significant at p below .001 without giving the difference in mmHg has withheld the finding. Communication marks depend on the answer leading and technical terms being defined once. Frequent deductions include pasting the output with no commentary, reporting p as .000, calling the difference proof that the program works despite a non-randomized design, and confusing the standard deviation with the standard error.

PU525 Unit 6 questions, answered
Which line of the SPSS t test table should the memo use?
Levene's test decides it. If its significance is above 0.05, the equal-variances row is normally used; if below, the row not assuming equal variances. The example states the Levene result and names the row it read. Many instructors accept either choice when it is justified, but a memo that reads a row without explaining why tends to lose a point.
Is a 5.8 mmHg difference meaningful for public health?
At the population level, a shift of that size is the scale prevention research treats as worthwhile, because small average reductions across many people prevent a meaningful number of strokes and heart attacks. The memo makes that point with a citation to the literature instead of inventing an event count, and pairs it with the design limitation so the claim stays proportionate.
Should the memo include the raw output?
As an attachment, usually yes, so every figure the memo quotes can be verified. The memo body should quote only the numbers it interprets. The example attaches the full SPSS tables and refers to them by block name, which keeps the two pages readable for a director without statistics training while leaving the evidence available to an analyst.
