It is a one-page presentation that tells a story about a set of data.
Here are some links to get a general picture about posters. These posters have been made to follow certain competition rules and may not meet the requirements of other competitions.
First find an issue or question to study.
It should be:
Before collecting data, plan carefully what measurements, etc. are needed. More about different types of data collection: http://www.statcan.gc.ca/edu/power-pouvoir/ch2/types/5214777-eng.htm.
When using data from other sources, they should be reliable and cited. More about the quality of statistics:
Don’t forget to consider randomness and numbers of measurements or observations.
If the topic is to find out students’ opinions and the study is only made by interviewing two best friends, the results may be severely biased.
If a problem is to measure how far a grasshopper can hop, measuring just one hop from one grasshopper won’t give good results. A bigger sample is needed. It is better, for example, to take 10 grasshoppers and measure 10 hops from each.

Do the data represent a general situation?
Data are variable (which is why we need statistics!) but also may have errors. What are the possible sources of errors in the data?
No matter how well the measurements or observations are made, there may still be some sources of variability or errors. Think about sources of variability or errors and if possible mention them in the poster. Suggestions on how the study could have been improved can also be given.
Analyze the data collected either by hand or by using some computer program.
Remember, you are investigating the original issue(s) or question(s).
Use numbers and graphs to describe the data. For example, histograms, bar charts, line charts, pie charts and box plots. Statistical quantities like mean, median or standard deviation are also useful.

Physical or electronic?
Posters may be:
Posters are not meant to be looked at for long but should:
Remember there is only limited space so don’t say things twice. Pick only the graphs that best present the results. Graphs should be titled and commented on.
