Conference of Texas Statisticians 2019

The Conference of Texas Statisticians (COTS) was established at the annual American Statistical Association (ASA) meeting in Houston, Texas in 1980. Tom Bratcher, Bill Schucany, and Jim Davenport organized the first COTS meeting which was held in Waco, Texas in February, 1981. The conference has been held annually since then. After the successful 1985 meeting in Austin, the Texas Chapters of the ASA were invited to set up the Council of Texas Statisticians with representatives from each Texas Chapter. The COTS meetings afford Texas statisticians the opportunity for social and intellectual exchange on a yearly basis. Senior and junior statisticians as well as students present their research talks or posters at the COTS. These meetings also stimulate increased chapter membership as well as visibility of the statistical profession in the state of Texas. A highlight of each meeting is presentation of the annual Don Owen Award for excellence in research, statistical consultation, and service to the statistical community

The Conference of Texas Statisticians (COTS) 2019 will be held on April 5th to 6th at Lamar University in Beaumont, Texas. Click here for COTS 2019 Booklet.

Specific Instructions for poster presentation

We suggest the poster to have a size of 36 by 48 inches, which is standard in sciences and engineering.

The goal of your poster is to be a visual guide to reference while you present your research. In your poster try to develop a clear and singular message. Identify and put emphasize on what you want your audience to take away from your work.

Guidelines to build up a poster:

  • Present the motivation of your research;
  • Present a short background of the topic presented;
  • Identify the most significant aspects in the field of study;
  • Select and report only key results;
  • Present the process of collecting data and data processing including relevant details only;
  • Highlight the novelty of your approach;
  • Identify and present the possible further development of the topic.
  • Figures should be large, clear, and well labeled. Make sure you have all the necessary figures.
  • Do not generate paragraphs of text. People will not read them! Instead use short phrases and bullet points, keeping text to the essentials.
  • Include enough information for someone to follow along if you are not there.
  • You need to practice your poster explanation several times. Ask both colleagues & non-experts.

 General structure of the poster:

  • Posters are read left to right, top to bottom.
  • Three column designs are common.
  • Less is more. Stick to the message.
  • Results and conclusion go on the right side of a poster.
  • Put references and acknowledgments at the bottom.
  • Either make all your own figures (preferred), or cite them appropriately. Avoid plagiarism.
  • Favor graphs over tables.
