NAME: 1993 New Car Data TYPE: Sample SIZE: 93 observations, 26 variables DESCRIPTIVE ABSTRACT: Specifications are given for 93 new car models for the 1993 year. Several measures are given to evaluate price, mpg ratings, engine size, body size, and features. SOURCES: _Consumer Reports: The 1993 Cars - Annual Auto Issue_ (April 1993), Yonkers, NY: Consumers Union. _PACE New Car & Truck 1993 Buying Guide_ (1993), Milwaukee, WI: Pace Publications Inc. VARIABLE DESCRIPTIONS: Line 1 Columns 1 - 14 Manufacturer 15 - 29 Model 30 - 36 Type Small, Sporty, Compact, Midsize, Large - as defined in the _Consumer Reports_ article 38 - 41 Minimum Price (in $1,000) - Price for basic version of this model 43 - 46 Midrange Price (in $1,000) - Average of Min and Max prices 48 - 51 Maximum Price (in $1,000) - Price for a premium version 53 - 54 City MPG (miles per gallon by EPA rating) 56 - 57 Highway MPG 59 - 59 Air Bags standard 0 = none, 1 = driver only, 2 = driver & passenger 61 - 61 Drive train type 0 = rear wheel drive 1 = front wheel drive 2 = all wheel drive 63 - 63 Number of cylinders 65 - 67 Engine size (liters) 69 - 71 Horsepower (maximum) 73 - 76 RPM (revs per minute at maximum horsepower) Line 2 Columns 1 - 4 Engine revolutions per mile (in highest gear) 6 - 6 Manual transmission available 0 = No, 1 = Yes 8 - 11 Fuel tank capacity (gallons) 13 - 13 Passenger capacity (persons) 15 - 17 Length (inches) 19 - 21 Wheelbase (inches) 23 - 24 Width (inches) 26 - 27 U-turn space (feet) 29 - 32 Rear seat room (inches) 34 - 35 Luggage capacity (cu. ft.) 37 - 40 Weight (pounds) 42 - 42 Domestic? 0 = non-U.S. manufacturer, 1 = U.S. manufacturer Values are aligned and delimited by blanks. Missing values are denoted with *. There are two data lines for each case. SPECIAL NOTES: The only missing values are for CYLINDERS in the rotary engine Mazda RX-7, REAR SEAT room for the two-seaters (Corvette and RX-7), and LUGGAGE capacity for the vans and two-seaters. WEIGHT is taken from the _Consumer Reports_ data and includes a full fuel tank, automatic transmission (if available), and air conditioning. STORY BEHIND THE DATA: Cars were selected at random from among 1993 passenger car models that were listed in both the _Consumer Reports_ issue and the _PACE Buying Guide_. Pickup trucks and Sport/Utility vehicles were eliminated due to incomplete information in the _Consumer Reports_ source. Duplicate models (e.g., Dodge Shadow and Plymouth Sundance) were listed at most once. A similar dataset for 1989 model cars appeared as one of the sample datasets shipped with the _Student Edition of Execustat_ (PWS-KENT 1990). Further description can be found in the \"Datasets and Stories\" article \"1993 New Car Data\" in the _Journal of Statistics Education_ (Lock 1993).

It includes many good numeric variables and several options for dividing the cars up into groups. Students tend to be familiar with most of the variables (and specific car models). They can anticipate and pose explanations for many of the relationships to be found in the data, although some surprises may be encountered. One can easily find examples of pairs of variables that demonstrate strong or weak, positive or negative associations. PRICE and MPG variables tend to be popular choices as \"dependent\" variables. Basic graphs will often reveal unusual data values (like the price for a Mercedes-Benz). REFERENCES: Lock, R. H.
