Sixteen thousand claimed conversions against 12,400 real orders open this GB794 Unit 4 attribution analysis, which then asks what each measurement method can and cannot establish. Searches like "gb 794 unit 4 assignment example", "gb794 unit 4 sample" and "gb794 unit 4 example" land here.
What a finished GB794 Unit 4 attribution analysis looks like
About eight pages carrying three exhibits. Exhibit 1 reconciles claims against the order system: platform-reported conversions sum to 16,000, the grocer's database holds 12,400 online orders, and the surplus of 3,600 is traced to overlapping click and view windows. Exhibit 2 follows one composite order, a shopper who watched an Instagram ad on Monday, searched the grocer's name on Wednesday and paid that evening, through four accounts of it: Meta's, Google's, the analytics tool's data-driven split and the mix model, which never sees individuals. Exhibit 3 compares the three method families by data required, question answered, main weakness and cost. The text then reports last spring's geo holdout, in which pausing Meta prospecting in six of twenty delivery zones implied incremental orders near a third of what Meta claimed.
How a GB794 Unit 4 example is structured
Bookkeeping comes before inference, in three steps. Reconciliation leads because a reader who learns that claimed conversions exceed real orders stops treating any platform report as a count of effects. The single traced order makes the mechanism concrete: two platforms each claim the whole sale because their rules allow it, and neither rule is wrong on its own terms. The comparison table then states each method family accurately. Multi-touch attribution divides credit among observed touches by rule or algorithm and describes converting paths without estimating what would have happened otherwise. Mix modeling regresses aggregate sales on spend over time, so its estimates rest on whatever spend variation history happened to supply. Incrementality tests, geo holdouts among them, compare exposed and unexposed groups directly but answer only for the period and channel tested. A calibration recommendation follows from that division of labor.
Claims reconciled against orders
Platform totals sit beside the order database line by line. The 3,600-order surplus is not fraud; it follows from each platform counting any conversion inside its own window, and the analysis shows the overlap before drawing a conclusion from it.
One order, four accounts
The Monday video view, the Wednesday search and the evening checkout run through each tool's rules. Meta credits the view, Google the click, the analytics model splits the sale, and the mix model registers only a week of higher spend and sales.
Three method families, stated accurately
Attribution describes paths, mix models estimate from aggregate variation in spend, and holdout experiments estimate incremental effect directly. Each row names what the method needs, what it answers and where it fails, including lost user-level tracking after Apple's 2021 App Tracking Transparency prompt.
Last spring's holdout
Meta prospecting paused in six randomly chosen zones for four weeks while fourteen continued. Orders in paused zones fell by an amount implying about 2,300 incremental orders per quarter, roughly a third of the platform's claim, and the interval is reported beside it.
Calibration instead of a single winner
The closing section recommends feeding holdout results into the mix model as priors and repeating a test every half year. Open-source tools such as Meta's Robyn and Google's Meridian support that calibration, and the analysis names them without endorsing either.
Where marks go in GB794 Unit 4
Treating any single tool's output as the truth is the first thing graders look for, whether it is the platform's report or a mix model presented as neutral arbiter. Descriptions of the three methods carry heavy weight, and inaccuracy is marked specifically: calling multi-touch attribution causal, claiming mix models need no historical spend variation, or implying a geo test measures every channel at once. An analysis that notices double counting but never reconciles against the order system leaves its central observation unquantified. The holdout needs its interval as well as its point estimate, since a third of the claim stated with no uncertainty reads as surer than four weeks in twenty zones allow. Naming one winning method ignores what each answers. Stronger papers end on a calibration routine a marketing team could run twice a year.

Pull the platform reports and order totals you are able to share, or describe the channels if the data are restricted, and add the Unit 4 prompt with its rubric. Reconciled against real orders, the analysis states each method's reach accurately and reports any experiment's uncertainty. It usually takes 24-48h, and a first sample carries no fee.
GB794 Unit 4 questions, answered
Is marketing mix modeling more reliable than multi-touch attribution?
Neither is reliable for every question. Mix models see all channels, offline ones included, but lean on historical variation in spend that may be tangled with seasonality and promotions. Attribution sees individual paths but not what would have happened without the ads. Experiments answer the counterfactual directly for the tested channel and period, which is why current practice uses them to calibrate the other two.
Why do platform-reported conversions exceed actual orders?
Each platform counts a conversion whenever its own rules connect it to an ad, using click and view windows it sets itself. When a shopper touches two platforms before buying, both can legitimately claim the same order. Summing platform reports therefore overstates the total, and reconciling them against the retailer's own order records makes the overlap visible.
Can the analysis rely on a platform's own lift study?
It can, provided the paper describes the design. Platform conversion lift studies randomize users into exposed and holdout groups, which gives them a genuine counterfactual, but the platform runs the test and reports the result. A doctoral paper notes that dependence, compares the estimate with independent evidence such as a geo holdout, and reports whatever uncertainty the study provides.
