Before any ad runs, GB531's Unit 9 campaign measurement plan fixes two survey waves, an unadvertised comparison market and the smallest change each measure can detect. Searches like "gb 531 unit 9 assignment example", "gb531 unit 9 sample" and "gb531 unit 9 example" land here.
What a finished GB531 Unit 9 campaign measurement plan looks like
Six pages built on a measures table and a design diagram. Measures map to the Unit 2 objectives: whether target homeowners link the brand with nothing to refuel, stated likelihood of requesting a quote, and quote requests counted per 10,000 target households from the electricians' booking system, sorted by ZIP code. The design is a difference-in-differences comparison: 400 interviews per test market per wave, 1,200 in all, against 600 per wave in Baton Rouge, which receives no advertising but shares the region's storm exposure. Detection limits are computed for each measure: about 7.6 points for association and 5.7 for consideration, the second reached only after raising the Baton Rouge sample from 400, where it stood at 6.5. Clicks, video completions and search volume are reported but never judged.
How a GB531 Unit 9 example is structured
The plan begins with the objectives verbatim, because a measurement plan exists to judge them and should not restate them in softer words. Each measure then receives a row: its source, its timing, its comparison and the decision it informs. The design section explains why a comparison market is needed at all: storms and outages move interest in backup power regardless of advertising, and without an unadvertised market a hurricane season could be credited to the campaign. The detection-limit arithmetic follows, shown once with the formula, and the paper flags that the six-point consideration objective sat below the original design's limit, prompting a larger Baton Rouge sample at about $12,000 more. A rule for outages during the flight is written down: weeks with a 24-hour outage in any test market are reported both with and without.
The Unit 2 objectives, word for word
Seventeen to 35 percent association by July 15, nine to 15 percent consideration, and a quote-rate gain over the comparison market. Copying them exactly prevents the plan from quietly measuring something easier.
Why Baton Rouge
A market close enough to share the region's storms and outage habits, carrying no campaign weight. Without it, a rough season would lift quote requests everywhere and hand the credit to the advertising.
Detection limits before launch
With 1,200 test interviews and 400 in the comparison market, the smallest reliable change was 8.8 points for association and 6.5 for consideration. The six-point consideration goal could not have been judged at all.
A bigger comparison sample
Raising Baton Rouge to 600 per wave lowers the limits to 7.6 and 5.7 points, at about $12,000 more. The plan records that choice as the cost of making the second objective testable.
A rule for storms during the flight
Any week with a 24-hour outage in a test market is flagged, and quote results are reported with and without those weeks. The rule is fixed now, so nobody picks the flattering version later.
Where marks go in GB531 Unit 9
Listing metrics the campaign will report, rather than tests it could fail, is the central weakness graders find in GB531 measurement plans: counting clicks is not judging an objective. Plans with no baseline, or a baseline taken after launch, cannot show change. Designs lacking any comparison leave outside events, a storm season here, indistinguishable from advertising effects, and many graduate rubrics reward a control or comparison of some kind. Sample sizes chosen without asking what change they can detect are a quieter loss. A measure with no matching objective breaks the thread from Unit 2. Plans that allow results to be reported selectively, with no rule set in advance for disruptions, draw comment in sections that grade rigor.

Copy your campaign's objectives word for word, list the markets involved, and add the Unit 9 prompt and rubric. The custom measurement plan maps every objective to a test it could fail and states detection limits, returning free as a first sample in 24-48h. Survey costs without a quote are labeled estimates.
GB531 Unit 9 questions, answered
Do I need a control market in a course measurement plan?
Not always, but some form of comparison strengthens any plan: an unadvertised market, a holdout group of households, or the same weeks in a prior year. Without one, the plan can show change but not cause. If your section's scenario offers no comparison, say so and name what else could have produced the change.
How do I work out the smallest change a survey can detect?
For comparing two proportions, the standard error depends on the proportion and the sample sizes; multiplying it by about 2.8 gives the change detectable with 80 percent power at the usual 5 percent significance level. Show the formula once with your figures. If a target falls below the limit, enlarge the sample or revise the target.
Should clicks and impressions appear in the plan?
They can, as delivery measures showing the campaign ran as bought. They should not stand in for objectives unless an objective is itself about response online. Separate the two in the plan: what confirms the media ran, and what judges whether the advertising worked. Graders in many sections look for that distinction.
