Apples and Pears, Year Ending March 1998
Contents
I. Data Processing, Estimation, and Analysis
I1 Follow-up activities
What steps will be taken to ensure the expected response rate is achieved? (I1)
Note. Should detail planned follow-up procedures.
The priorities for following up non-response are:
- units with large EVAO (ie most significant units within the industry); and
- chronic non-respondents

I2 Data entry and coding
What quality control procedures will there be for data entry and coding? (I2)
Note. Examples of quality control procedures include: clerical scrutiny of forms, on-line edits, and the like.
The type of checks done prior to data entry include a minor clerical scan of the form and recontact the respondent where necessary.
The versions of the Survey Data File stored are: Publication version, SDF is continually updated. Regular backups stored.
Batch edits include logical, comparative and range edits. Amendments overwrite original data. Priority in batch editing is given to fatal edits (e.g. production but no trees). Query edits involving large units are also high-priority.
Significance editing is especially important during aggregate editing, and involves historical comparisons (area and production) and checks of current year yields. These are ranked by importance to contribution to estimates.

I3 Outliers
Will outliers be identified, and, if so, how will they be handled? (I3)
Unexpected results are handled by normal editing procedures (check of form, contact with respondent).

I4 Non-sampling error
What sources of non-sampling error could have a significant impact on survey results and what is being done about them? (I4)
Note. Should include: what imputation procedures will be used; what known frame deficiencies are to be treated in estimation; and what other allowances will be made for other potential sources of non-sampling error in estimation.
The key quality problems of the collection are:
Owner/operator information - obtain different business structure from the front of the form.
Mis-reporting of data items.
Non-response.
Editing procedures include Hot Deck Imputation and Clerical Imputation
This collection does not use New Business Provisions.
Population counts are changed as new births and deaths to the population are detected.

I5 Aggregation of data
Will data be aggregated into statistical tables, and if so what are the estimation formulae for the principal output data items? (I5) Note. Should include how adjustments for outliers, imputation and frame undercoverage factors have been incorporated into estimation formulae, and the variance formulae for variances that are to be published.
Data will be aggregated into statistical tables.
Estimation: n/a

I6 Analysis of results
How are the results of the survey to be analysed? (I6)
The data will be analysed through the production of tables of data items.

I7 Availability of results
How are the results of the survey to be made available to the major users? (I7)
The Apples and Pears collection contributes to Australian and State agricultural compendia and to:
7116.0 - Ag Stats on Magnetic Tape
7117.0 - AgStats on floppy disk
7117.0.30.001 AgStats on CD-ROM
- A regional profile product offering small area commodity statistics for all States and Territories. The data include information on livestock numbers and area and production of crops and pastures.
Integrated Regional Database (IRDB)
Data is available through information consultancies using AgStats, mainframe files or other sources of material. These can be provided by ALOs (Agricultural Liaison Officers), information consultancy staff in each state, or staff in Data Management Section in Hobart NPC, and staff in Central Office.

I8 Performance measures
What processing performance measures have been defined? (I8)
Note. This question is concerned with processes that are in place to ensure that the timetable deadlines will be met, eg responses received by date, percentage of data captured by date, percentage of data edited by date, etc.
The content of the Management Information System includes: Processing rates by edit status, Response rates by categories (sampled and CEd etc)

I9 Systems Testing
How have the data processing, aggregation and dissemination systems been tested? (I9)
These systems will be the same as those used in previous collections. There are no changes to the collection that warrant testing of these systems.
