Before paying for a survey, this Unit 3 review in GB532 checks delivery tickets, weather records, price series and rebate counts, and finds weather explains most of a propane firm's decline.

What a finished GB532 Unit 3 secondary data review looks like
Six pages built around a source table and one decomposition. The table lists five sources with columns for who collected the data, why, how current it is, what it covers and what it cannot tell the firm. Internal delivery tickets come first, since each fill records gallons and a date, which lets the review compute every account's K-factor, the degree days it takes that household to burn one gallon. Heating degree days come from the nearest weather station, weekly residential propane prices from the Energy Information Administration, household heating fuel from the American Community Survey, and heat pump rebates by town from the state efficiency program. The decomposition assigns about three-fifths of the 11 percent drop to weather, under a fifth to departed accounts and roughly a quarter to lower use per remaining home.
How a GB532 Unit 3 example is structured
Internal data precede external because the cheapest evidence is what the firm already owns. Each source then gets the same four-part treatment: origin and purpose, coverage, recency, and fit to the Unit 2 objectives. That parallel form lets a reader compare sources quickly and keeps the review from becoming a list of links. Evaluation is explicit, since a secondary source collected for another purpose can mislead; the Census heating fuel item, for example, records a main fuel only, so a hybrid home appears as propane or as electricity but never both. The decomposition follows the source table and uses only its figures. A short section then flags 1,140 automatic accounts whose K-factor rose 25 percent or more, the likeliest heat pump homes. The review closes by stating what still needs primary data: why those households changed and whether they would buy a backup plan.
Tickets that already measure use
Every automatic fill records gallons and date. Divided into the degree days between fills, those tickets give a K-factor per account, a usage signal that exists before anyone designs a survey.
Weather taken out first
Degree days fell 6.5 percent against the prior winter. Removing that effect, and the 2.1 percent of accounts that left, leaves a decline of about 2.8 percent in use per remaining household.
What the Census item cannot see
The American Community Survey asks for a home's main heating fuel. A house running a heat pump until the coldest weeks may still report propane, so the review treats that table as context, not as a count.
Rebate counts by town
Published counts of rebated heat pumps show installations concentrated in a handful of towns along the firm's northern routes. The review maps them against the flagged accounts and finds substantial overlap.
Gaps only customers can fill
No record says why a household added a heat pump, how it now splits heating between fuels, or what it would pay to keep propane as backup. Those three gaps define the study proposed in Unit 4.
Where marks go in GB532 Unit 3
Evaluation outweighs collection when a GB532 secondary review is graded. A list of databases with no comment on who gathered them, when, or for what purpose earns the description row and little else. Graders reward the moment a source's limits are stated plainly, such as a Census item recording one main fuel, because that is the difference between reading data and trusting it. Internal records are an easy credit to miss; reviews that skip straight to government sources ignore what the firm already knows. Currency matters too, and a price series from three seasons ago needs a reason to appear. Reviews that stop before saying what remains unanswered leave the proposal unit without a foundation. Claims about what a source contains, unsupported by a citation, draw comments quickly.

GB532 Unit 3 questions, answered
How many secondary sources does the review need?
Enough to cover the objectives, which in most GB532 sections means four to six, with at least one internal. More sources rarely help if each gets a sentence. The grade tends to follow the evaluation of each source, so five sources assessed on origin, coverage, recency and fit outscore a dozen that are merely named.
Can internal company records count as secondary data?
Yes. Secondary means collected for another purpose, and sales records, delivery tickets and service logs were gathered to run the business, not to answer your research question. They are often the most relevant source available. If they belong to your employer, describe them in general terms and round any figures you report.
Should the review include analysis or just describe sources?
A light analysis usually strengthens it, because showing what the sources already answer is the best argument for what they do not. Where the prompt asks only for evaluation, keep calculations brief. The example's decomposition takes one paragraph and one table, and it changes the size of the problem the rest of the project addresses.
