Tabulation Pdf
Adabella Frierdich
In my quest to avoid the table-flashing behavior of JMP I'm trying a different approach. Normally I create an invisible tabulation, and to use the data I make a data table out of it. The data table is easy to use, but unfortunately if you create a lot of them (like I do) you get lots of tables appearing and disappearing.
Try this example and you'll see what I'm talking about. I notice that the table "flashing" is much more pronounced in JMP 9 running on Windows XP. It wasn't so bad in JMP 8. Seems like separate window creation under Windows 7is "cheaper", hence it's faster.
Section 207(f)(2) of the E-Government Act of 2002 requires federal agencies to develop an inventory of information to be published on their Web sites, establish a schedule for publishing information, make those schedules available for public comment, and post the schedules and priorities on the Web site.
Requests for Special Tabulations are considered when the requested data are not published elsewhere. The Quick Stats agricultural data base should be investigated before requesting a special tabulation. The reports, related to these resources can be accessed from the Census of Agriculture and Publications pages.Special TabulationsSpecial tabulations are publishable, resummarized data tables from the Census of Agriculture or NASS surveys. The special tabulations differ from NASS published reports in the following ways:
All requests must be scheduled so that they do not interfere with the requirements of NASS operational work. Most special tabulations are expected to take from weeks to several months to complete depending on workloads and complexity.
Special Note on Timing: While the 2022 Census of Agriculture reports are being prepared, no special tabulation requests for the census of agriculture program data will be accepted until August 1, 2024.
Fees are calculated based on the resources required to complete the tabulation and disclosure review. More complex requests will consume more resources and have higher cost estimates. The minimum cost for a special tabulation is $1,500. NASS cannot begin programming new special tabulations until the request has been approved by the Data Access and Disclosure Review Board, a Statement of Work is signed, and payment is received. For non-federal clients, NASS accepts payment by check, ACH, or Fedwire. Payment instructions will be sent with the invoice. Any fees to send an ACH or Fedwire are the responsibility of the client. Federal clients must pay for special tabulations through an Interagency Agreement.
To request a special tabulation, the client must provide a preliminary specification of the data needed by completing the request form below and submitting the signed form to the NASS Data Lab and Data Access Group at SM.NASS....@usda.gov. NASS will then follow up and work with the client to develop a final, detailed specification. This specification is sent to the Data Access and Disclosure Review Board for consideration. Special tabulation requests are reviewed on an individual basis to determine what expertise, resources, and technology are needed to complete each tabulation. All special tabulation requests will be reviewed for disclosure limitations and fitness-for-use and are subject to approval by the Data Access and Disclosure Review Board. A statement of work and cost estimate will be delivered to the client after the specification is approved.
Applications requesting Census of Agriculture data for years 2007 or newer are required to provide a variable list. The list can be downloaded from this website and completed lists can be emailed to SM.NASS....@usda.gov with your SAP application number.

NASS does not charge researchers for use of our data. We do use the services of a data enclave provider, which provides a secure environment to researchers to access data while administering confidentiality protections. When your project is approved for access to NASS restricted microdata using a data enclave, you will be required to pay initial user setup and annual user fees to the data enclave provider for data enclave access. Invoicing is handled by the data enclave provider. Each data enclave account is non-transferrable and cannot be shared. Accounts within the data enclave are created for individual researchers. Projects can have more than one researcher. Each researcher will have a dedicated project space and access to a joint project space within the data enclave.
Data enclave fees depend on workspace performance configuration options and number of researchers. Effective August 2023, the fees for the data enclave are approximately $600 per user setup plus $2,000 - $2,300 annually per user. Researcher requests for services above the base workspace may incur additional fees. All fees are subject to change.
When collecting data, NASS makes a pledge of confidentiality to its respondents. This pledge promises that data collected are used for statistical purposes only. As a NASS sworn agent authorized to access and handle restricted NASS data, you are required to maintain the confidentiality of NASS data in accordance with the Confidential Information Protection and Statistical Efficiency Act (CIPSEA) of 2018, Title III of Pub. L. No. 115-435, codified in 44 U.S.C. Ch. 35. Penalties for a violation of CIPSEA procedures can result in a fine of up to $250,000 and/or five years in prison. Confidentiality training, confidentiality forms, and the Data Lab Handbook outline the policies and procedures that are required of you and your team to protect the data and prevent disclosure of confidential information. More information concerning confidentiality of NASS data collected for statistical purposes can be found here: Confidentiality Pledge.
When the researcher has completed work, NASS will conduct a disclosure review of all project outputs to ensure that data confidentiality is protected. The data enclave provider will facilitate your output clearance through NASS. Once cleared, the NASS Data Lab and Data Access Group will email you the outputs. Please contact the NASS Data Lab and Data Access Group at SM.NASS....@usda.gov if you have questions or concerns regarding the disclosure requirements for the data you are seeking.
CIPSEA protected data is not subject to Freedom of Information Act (FOIA) requests. If you are interested in obtaining documents maintained by the National Agricultural Statistics Service (NASS), you will find information on accessing both FOIA and non-FOIA records on the REE Freedom of Information Act and Privacy Act Guide website.
Cross-tabulation (also cross-tabulation or crosstab) is one of the most useful analytical tools and a mainstay of the market research industry. Cross-tabulation analysis, also known as contingency table analysis, is most often used to analyze categorical (nominal measurement scale) data.
At their core, cross-tabulations are simply data tables that present the results of the entire group of respondents, as well as results from subgroups of survey respondents. With them, you can examine relationships within the data that might not be readily apparent when only looking at total survey responses.
For reference, a cross-tabulation is a two- (or more) dimensional table that records the number (frequency) of respondents that have the specific characteristics described in the cells of the table. Cross-tabulation tables provide a wealth of information about the relationship between the variables.
For example, a categorical variable could be customer reviews by region. You divide this information into reviews per geographical area: North, South, East, West, or state, and then analyze the relationships between that data.
As a result, cross tabulation is excellent for assessing categorical variables in market research or survey responses, as you can readily compare data sets to discover the relationship between two (or more) seemingly unrelated items.
As a statistical analysis method that allows categorical evaluation across a data set, cross tabulation can help to uncover variables or multiple variables that affect a specific result or can aid in improving a specific outcome.
In Microsoft Excel, cross tabulation tables (or crosstabs) can be automated using the Pivot Table. You can either use the Pivot Table icon in the toolbar or click on Data > Pivot Table and Pivot Chart Report.
Alternatively, you can press Insert and then click the PivotChart button. Once clicked, the PivotChart dialog box will open. Select the data that should be used in your crosstab analysis and select where you want it to be placed.
Furthermore these probabilities are cumulative, meaning that if 20 tables are tested, the researcher can be almost assured that one of the tables is incorrectly found to have a relationship (20 x .05 = 100% chance). Depending on the cost of making mistakes, the researcher may apply more stringent criteria for declaring significance, such as .01 or .005.
In this example table, we observe that the chi-square value for the table is 19.35, and has an associated probability of occurring by chance less than one time in 1000. We therefore reject the null hypothesis of no difference and conclude that there must be a relationship between the variables. We can observe the relationship in two places in the table.
Crosstabs and chi-square are powerful ways to analyse your survey data. Another tool that makes an impact on research is Conjoint Analysis.
