[Informatics] Primary Quantitative Data - Any sources?

[Garth, Lucas A]

Hi Chris

My main thoughts would revolve around what you are looking at.  If you are accessing an unprocessed spreadsheet of data, I can see arguments for primary (though technically if the data is grouped by age or by location it is by definition value-added and secondary IMO).

If you are accessing an information report, such as "Internet Access at Home" http://abs.gov.au/AUSSTATS/abs@.nsf/Lookup/4102.0Chapter10002008 then this is clearly secondary.

I also suggest - you don't need just surveys to collect primary quantitative data, when observations could be just as usable depending on the hypothesis.  If your students are looking for opinions about the reasons behind a specific theory, then I'm not sure there are ways to collect it other than surveys, interviews, polls, questionnaires and observations.

Ok... so I found some raw data on the ABS site that would be good to use.
http://www.cas.abs.gov.au/cgi-local/cassampler.pl

However I would still like to know categorically. (maybe Paula Christophersen could weigh in on this one)
 Is a graph or found on the ABS site considered a primary source?
Am I getting primary data and primary sources confused?

I would love for someone to tell me that we don't need students to conduct surveys to get primary quantitative data!

Thanks
Chris

I have decided it's really up to you as a teacher. There is a difference between primary data and primary data source. I believe the ABS would be a primary data source as would AFL stats etc and their data would cover the primary source quantitative component. A news report or Wikipedia would be a secondary data source. The study design, SAT info doc and rubric only mentions "primary and secondary data sources". I actually can't see anywhere where it says students have to go out and do interviews and surveys for the SAT. Can you?

I feel I'm short on time both in preparation and in undertaking the task. It would be great if we were discussing this 12 months ago. It is going to be difficult to for students to find a feasible hypothesis and a lot of time is going to be spent teaching them how to do this. Therefore, this year at least,  I'm going to keep this as simple as possible.

This is interesting from the Study Design:
Informatics U3O2:
                primary and secondary data sources (digital and non digital) and
methods of data acquisition, including observation, interview and querying of resources
Software Development U3O2:
techniques for collecting data to determine needs and requirements, including interviews, surveys and observation

Why not surveying in Informatics?

Hello all.

I was getting my students to do a bit a check on their hypothesis today to make sure they could gather all the data needed to get a good mark. They were looking for primary quantitative data.

Am I right in thinking that the only real source of primary quantitative data is that gathered by the student in surveys?
It is hard to consider ABS stats as primary quantitative because the ABS do not offer raw/unedited/non value added data on the website. Therefore should the ABS stats and data be used as secondary quantitative?

If anyone else has some good primary quantitative data sources I would love to see them.

Thanks,
