AIDS | The total number of cases of AIDS in the USA in 4 month intervals from 1982. | Increasing, Concave Down |

BADMIN | This data set was obtained by dropping a badminton shuttlecock and recording its distance as a function of time. | Increasing, Concave Up |

BRAKE | The distance in feet a car travels when braking in an emergency stop as a function of the velocity of the car at the time the brakes are applied. | Increasing, Concave Up |

BULLET | A bullet was shot from a rifle. The velocity was measured as a function of distance traveled. | Decreasing, Concave Up |

CAR | A car with manual transmission was driven on a long straight horizontal road at 55 mph. The car was taken out of gear and let roll to a stop. The time at which the car was traveling at 55, 50, ... , 10, 5, and 0 mph was recorded. | Decreasing, Concave Up |

COFFEE | Some students measured the temperature of coffee to see how rapidly it cooled. The coffee temperature is shown as a function of the time. | Decreasing, Concave Up |

CRAB | The claw weight versus body weight of fiddler-crabs. | Increasing, Concave Up |

DENECKE | Paul Denecke, The University of Arizona, conducted the following experiment using a VCR equipped with a digital tape-counter. He put a tape in the unit, set the tapecounter to zero, and, as he started the tape playing, noted the time. He then kept recording the time and the number on the tapecounter. This data set was obtained in this way. It shows the number of revolutions - the number on the tapecounter - as a function of time in seconds. | Increasing, Concave Up |

FREEFALL | This shows data that correspond to a sky diver in free fall in a stable spread-eagle position when falling from rest. It shows the sky diver's distance fallen as a function of the time. | Increasing, Concave Up |

JUMPS | The results of an experiment in which people fell freely from rest from various heights. It shows the distance fallen in feet as a function of time in seconds. | Increasing, Concave Up |

KENYA | The population of Kenya for the period 1955 to 1990 in 5 year intervals. | Increasing, Concave Up |

LEWIS | The times achieved every 10 meters by Carl Lewis in the 100 meter final of the World Championship in Rome in 1987. | Increasing, Concave Up |

LIZARD | Experiments have been performed where a lizard is encouraged to run as fast as possible, starting from rest. The distance run is then measured as a function of time. | Increasing, Concave Up |

NICOTINE | Nicotine Sulphate is introduced into a closed room containing mosquitoes to determine how efficiently the chemical kills the insects. This shows the killing efficiency - the proportion of dead mosquitoes - for various doses. | Increasing, Sigmoidal |

PLAICE | The results of an experiment relating the weight of plaice to its length. | Increasing, Concave Up |

PROBE | A student held a temperature probe firmly between her thumb and forefinger while the temperature of the probe was recorded. This shows the temperature as a function of the time. | Increasing, Concave Down |

RANGE | The results of an experiment recording the range of a projectile as a function of the initial angle of elevation. | Increasing, Decreasing, Concave Down |

SPHERE | The data set was obtained by dropping a Styrofoam ball and recording its distance as a function of time. | Increasing, Concave Up |

STURGEON | A biologist measured the length of a sturgeon over a 21 year period. This shows the length in centimeters as a function of the time in years. | Increasing, Concave Down |

TAPE | Conduct the following experiment using either a VCR or a tape deck equipped with a digital tape-counter. Put a tape in the unit, set the tapecounter to zero, and, as you start the tape playing, note the time. Then record the time every 5 to 10 minutes along with the number on the tapecounter. This data set was obtained in this way. It shows the number of revolutions - the number on the tapecounter - as a function of time in seconds. | Increasing, Concave Down |

TOLUENE | The vapor pressure as a function of temperature of Toluene. | Increasing, Concave Up |

USAPOP | The population of the USA from 1790 to 1990 in 10 year intervals. | Increasing, Concave Up |
