dataset file (.txt or .dat.txt)
TYPE: e.g., Random sample, Census, Time series, Designed experiment,...

ARTICLE TITLE: Title of the article, when appropriate
A brief (no more than 10 lines) description of the dataset.
Acknowledge any published data sources or give brief description of origins of the data.
Provide a "key" for reading the ASCII data file. Explain how the data is delimited (tab, comma, space, etc.),any variable codings (including missing values) and/or measurement units.
Describe any special circumstances which should be brought to the attention of persons attempting to analyze the data.
STORY BEHIND THE DATA:
A brief narrative describing the origins of the data and the reasons they were collected. This is a good place to supply any background needed to understand the underlying variables, describe relevant issues, and suggest questions which might be of interest. This and the next section should be fairly concise. If you find them getting too long -- it's time to write a full "Datasets" article!
Suggest some ways an instructor might use the data in class. Describe any interesting features and/or statistical concepts which are well illustrated.
Include any references not in the SOURCES section.
(This gives you credit and provides a source for instructors who find the data useful to get clarifications if needed.)
