This was the 1983 ASA Data Exposition dataset. The dataset was collected by Ernesto Ramos and David Donoho and dealt with automobiles. Data on mpg, cylinders, displacement, etc. (8 variables) for 406 different cars. The dataset includes the names of the cars.

The Committee on Statistical Graphics of the American Statistical Association (ASA) invites you to participate in its Second (1983) Exposition of Statistical Graphics Technology. The purposes of the Exposition are (l) to provide a forum in which users and providers of statistical graphics technology can

exchange information and ideas and (2) to expose those members of the ASA community who are less familiar with statistical graphics to its capabilities and potential benefits to them. The Exposition wil1 be held in conjunction with the Annual Meetings in Toronto, August 15-18, 1983 and is tentatively scheduled for the afternoon of Wednesday, August 17.

Seven providers of statistical graphics technology participated in the l982 Exposition. By all accounts, the Exposition was well received by the ASA community and was a worthwhile experience for the participants. We hope to have those seven involved again this year, along with as many new

participants as we can muster. The 1982 Exposition was summarized in a

paper to appear in the Proceeding of the Statistical Computing Section. A copy of that paper is enclosed for your information.

The basic format of the 1983 Exposition will be similar to that of 1982.

However, based upon comments received and experience gained, there are some changes. The basic structure, intended to be simpler and more flexible than last year, is as follows:

A fixed data set is to be analyzed. This data set is a version of the CRCARS data set of

Donoho, David and Ramos, Ernesto (1982), ``PRIMDATA: ata Sets for Use With PRIM-H'' (DRAFT).

Because of the Committee's limited (zero) budget for the Exposition, we are forced to provide the data in hardcopy form only (enclosed). (Sorry!)

There are 406 observations on the following 8 variables: MPG (miles per gallon), # cylinders, engine displacement (cu. inches), horsepower, vehicle weight (lbs.), time to accelerate from O to 60 mph (sec.), model year (modulo 100), and origin of car (1. American, 2. European,

3. Japanese). These data appear on seven pages. Also provided are the car labels (types) in the same order as the 8 variables on seven separate pages. Missing data values are marked by series of question marks.

You are asked to analyze these data using your statistical graphics software. Your objective should be to achieve graphical displays which will be

meaningful to the viewers and highlight relevant aspects of the data. If you can best achieve this using simple graphical formats,
