3 Overview of TDR and The interface to Survey data – TDR: TUG interface – : OCUL interface Formats/Types of files: raw data, Excel, B2020 Search or browse surveys Subset the survey Download the data for analysis Access the documentation NB: Nesstar is the software running behind both TDR and for data download and subsetting

4 Overview of TDR and Terminology to know… – Metadata: data describing the data (i.e., the data’s catalogue record) Study Description (Biblographic Citation, Study Scope, Methodology and Processing, Data Access) Data Files Description Other Documentation (codebooks, user guides, etc.) – Variables: the questions asked – PUMF: public use microdata file – Synthetic file: data are all mixed up – these files should be used only for testing syntax of programs

5 Overview of TDR and Nesstar symbols to know: – + : click to open (not at the survey yet!) – Grid: click to open (at title of survey) – Funnel: subset button – Disk: download button

6 Overview of TDR and Uses the drilldown method for Browsing – Major category – Year – Geography – Survey Remember the symbols? – Click on them to get where you need to be! Clicking on the title of the product retrieves the Abstract Documentation is under Metadata  Other Documentation May vary slightly depending on what’s available

7 Overview of TDR and Slightly different for - and includes French Major Categories (TDR)

TDR vs : when to use TDR to download known datasets and/or documentation to identify, locate, or access datasets and other statistical or data files not on (e.g., non-web-based Statistics Canada products, such as InterCorporate Ownership, and those from 3 rd party sources, such as SourceOECD) for searching for public opinion polls (Gallup, CORA, etc.) if TDR is down! 8 Think of it as TRELLIS vs Primo!
