Q. I don't understand the use of tabs on the Statistical Product pages?

A. An ABS product is arranged in a series of tabbed pages. Each tab contains components of the product, or information to help you better understand the product and use it to suit your requirements. For example the 'Summary' tab gives you a broad overview of information included in the product.

How to use other tabs can be found in the tabs guide.

Q. What classifications does the ABS use?

A. The ABS uses classifications for Geography, Industry, Occupation, Commodity and other classifications. To learn more about these visit the Methods and Standards page on the ABS website.

Q. What is meant by Time Series?

A. A Time Series is a collection of observations of well-defined data items obtained through repeated measurements over time. For example, measuring the value of retail sales each month of the year would comprise a time series. This is because sales revenue is well defined, and consistently measured at equally spaced intervals. Data collected irregularly or only once are not time series.

Q. Is there any information to help me understand Time Series Analysis?

A. There is a variety of information regarding the basic concepts; the process of seasonal adjustment; issues with seasonal adjustment; and seasonal adjustment methods on the ABS web site; see help using time series data for common questions around these and other reading.

Q. Does the ABS provide any statistical training?

A. The ABS offers a large suite of training programmes to develop your statistical skills and help you make the best use of ABS information. These courses are offered state wide, see Training calendar for further information.

The ABS also offers self help resources in the form of online training and understanding statistics tools.

Q. What are data cubes?

A. A data cube can be thought of as a set of similar 2D tables stacked on top of each other. For example, a set of 2D tables showing population at 30 June by age group for each local government area would form a data cube, with local government area s the third dimension.
