Data and Statistics

Comparing Data and Statistics by using ingredients and a recipe.

Imagine you look at a recipe. Data are your ingredients and Statistics are the final product.

Observational - What you capture in real-time.
Experimental - What you produce in your lab classes.
Simulation - Modeling / Machine-generated.
Derived - Text mining, 3D models.
Textual - Field or Lab notebooks.
Discipline-specific - E.g., Viewing stars through a telescope.
Instrument-specific - E.g., Taking your body temperature.

Gray Literature and PrePrints

Gray literature is the information created by organizations such as government agencies, professional associations, research institutes, and think tanks that are not published in scholarly journals or books. This includes:

  • Technical papers
  • Government reports
  • White papers
  • Theses & Dissertations 
  • Conference Proceedings
  • Pre-print journal articles

Gray literature is produced by researchers and practitioners in a field and is an important component of a thorough literature review due to its depth and breadth, timeliness, flexibility, and open access.

Preprints are research manuscripts posted to a public server prior to formal peer-review. They are also known as ePrints or electronic preprints. Essentially, they allow researchers to share their research on an initial basis while they finalize some things. Preprints are made available on specified servers designed to carry this content.


You can publish your manuscripts on preprint servers, if you want. Though there are some considerations:

Advantages

  • No access barriers - It's free for authors and readers! This increases the research's visibility.
  • Opportunities for early feedback and scholarly discourse.
  • Potential research acceleration - Publish and disseminate your research quicker.
  • Some repositories assign DOIs.
  • A priority date is established for the research findings.

Disadvantages

  • Not peer-reviewed - Concerns for credibility and distinguishing between high- or low-quality research.
  • Not all formats are accepted.
  • Agreement is required from all co-authors to submit a preprint.
  • Some preprint users don't disclose they used preprint research nor understand the limitations of preprints.
  • Some funders and publishers discourage preprint usage nor accept articles previously published as preprints.
  • Could possibly affect the patentability of an underlying invention.

Other Considerations

  • Licensing
    • Adding a license (e.g., Creative Commons) can inform others how to reuse your work.
    • Different versions of a preprint may have different licensing.
    • Journals have different policies around preprints, embargo periods, and post-publication distribution.
  • Versioning
    • Link different preprint versions
    • Link to the final, published version.
  • Sustainability
    • What is the long-term maintenance of preprint servers?
    • Affordability and commercial publishing.
  • Quality Control
    • Not a peer-review process
    • Server moderators and staff are often volunteers who filter out:
      • Works not within the server's scope.
      • Non-research articles.
      • Plagiarism, copyright infringement, and other ethical issues.
      • Incomplete works.
      • Non-scholarly works.

Recommendations

  • Choose the server that most aligns with your scope.
  • Do not post to multiple servers.
  • Link to the final, peer-reviewed versions when possible!

Patents

What is a patent?

patent is the intellectual property right granted by the U.S. Government to an inventor "to exclude others from making, using, offering for sale, or selling the invention throughout the U.S. or importing the invention into the U.S." for a limited time in exchange for public disclosure of the invention when the patent is granted. In most cases, this is twenty years from the date of application. In some situations, the term of the patent may be extended due to delays in the processing of the application. After the patent has expired, the invention becomes public domain. In addition, patent owners must pay a maintenance fee at 3.5, 7.5, and 11.5 years after issue or else the patent will expire.

See "How to Read a U.S. Patent" from Queen's University Library for a detailed description of the sections of a U.S. patent.

Patent Types

Utility patent: Describes a new and useful process, machine, article of manufacture, or composition of matter, or useful improvement thereof (i.e. what something does)

Design patent: A new, original, and ornamental design for an article of manufacture (i.e. how something looks)

Plant patent: Describes an asexually reproduced distinct and new variety of plant (e.g. ‘NuMex Heritage 6-4’ New Mexican Chile Pepper)

How do I search?

You can begin your search the following way:

  1. Brainstorm keywords to describe your invention, such as synonyms.
  2. Use your keywords to search for a similar match of your invention in Google Patents. The advanced search lets you enter phrases, exclude words, etc.
  3. If you find a similar invention, write down its class and subclass.
  4. Use the class and subclass to search patents and patent applications with the USPTO website classification search. The USPTO website is more current than Google Patents.
    1. [Note: The default search is CPC (Cooperative Patent Classification), which harmonizes the former European Classification (ECLA) and United States Patent Classification (USPC) systems.]
  5. Trace related patents through references.

Why should I search first?

You have an idea for an invention — or have gone so far as to create a prototype. Before marketing your invention, you will need to determine if your invention has already been patented. To do this, conduct a thorough patent search. This will usually involve searching a number of different patent sites, so it's useful to keep a log of all your search activity to avoid duplicate efforts.

See General Information Concerning Patents and Patent Process Overview for more information.

Technical Reports

What are technical reports?

Technical reports describe the process, progress, or results of technical or scientific research. Include in-depth experimental details, data, and results.

Why should I use them?

Technical reports are usually produced to report on a specific research need. They can serve as a report of accountability to the organization funding the research. They provides access to the information before it is published elsewhere.

Are they peer-reviewed?

Technical Reports are usually not peer-reviewed.  They need to be evaluated on how the problem, research method, and results are described.
