Record by record, the Week 8 data source audit example in PUBH 8503 traces each variable the time series needs to its system, its keeper, its link and its gaps. Searches like "pubh 8503 week 8 assignment example", "pubh8503 week 8 sample" and "pubh 8503 week 8 example" land here.
What a finished PUBH 8503 Week 8 data source audit looks like
A variable-by-source matrix carries this three-page audit. Rows list the variables the study needs: antibody test date and result, RNA order, specimen collection, RNA result and date, visit type, recorded housing, age band and the month of the switch. Columns list four sources. The laboratory information system holds most of the testing fields and shows the switch as a change in order codes, which fixes the month objectively. The visit record holds demographics and visit type, linked to laboratory records by an internal identifier. The callback spreadsheet is incomplete and kept by hand, so it is excluded, with the reason stated. The state registry would reveal confirmations done elsewhere but cannot be linked within the study's timeline. The audit ends by naming who would need to approve an extract, noting that approval remains to be requested.
How a PUBH 8503 Week 8 example is structured
A matrix of variables against sources lets a reader check at a glance whether every variable has a home, and it shows where one source must stand in for another. Rows come first in the order the analysis uses them, so the outcome's components appear together. The audit notes how the switch month is identified, from a change in order codes rather than from staff memory, because the time series depends on placing that break exactly. Excluding the callback spreadsheet is stated rather than silent, since a reader would otherwise ask why an obvious record was ignored. The registry's limitation is recorded here in full because it will force a change to the outcome definition in the next week, and the audit is where that consequence first becomes unavoidable. The approval section closes the audit and describes permission as still to be sought.
Variables against sources
A matrix showing where each needed field lives, from antibody result to the switch month.
The switch, dated by order codes
The laboratory system marks the change in its order codes, fixing the break point without relying on memory.
A link by internal identifier
Visit records and laboratory records joined through the clinic's own identifier, with known mismatches noted.
A spreadsheet left out
The hand-kept callback log excluded for incompleteness, with the reason given.
The registry out of reach
Outside confirmations would appear there, but no link can be made within the timeline.
Where marks go in PUBH 8503 Week 8
Record-level precision is the audit's standard. Saying data will come from clinic records tells a reader nothing; tracing each variable to a system, a keeper and a link earns the central share. Identifying the switch month from order codes draws particular credit because the time series depends on dating that break exactly. Faculty reward stated exclusions, the callback spreadsheet here, over silent ones. The registry section is credited for recording a limitation that will change the outcome definition, showing the author sees the consequence coming. The approval section earns its share by describing permission as still to be requested. Audits are penalized for variables with no source, for link keys assumed rather than checked, and for any wording that implies data access has already been granted.

PUBH 8503 Week 8 questions, answered
Why exclude a data source that exists?
Because an incomplete source can mislead more than a missing one. The callback spreadsheet records some attempts and not others, so using it would suggest patterns that reflect record-keeping rather than practice. The example excludes it and states why. Your audit should do the same for any source whose gaps you cannot measure.
What if a key source cannot be linked in time?
Then the study must change to fit what can be linked, and the audit is where you discover this. The example finds the state registry out of reach and records it, which forces the outcome definition to narrow next week. Your approach is stronger for adjusting to the data than for promising a link you cannot deliver.
Does the audit need the approvals already in place?
No. The audit identifies who must approve access and marks those approvals as pending. Securing them runs through your institution's and the data holder's own processes. Describing access as granted before it is would be a serious misstatement, and faculty read for it. The approval section simply names each gatekeeper and the request each will receive.
