FILE | DESCRIPTION | PROPERTIES |

BACTERIA | The growth of a bacterial colony as a function of time. | Increasing, Sigmoidal |

BEANS | Beans were placed in a styrofoam cup, covered them lightly with soil, and watered regularly. On the tenth day sprouts emerged. This shows the height as a function of time. | Increasing, Sigmoidal |

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

CYNTHIA | Cynthia's approximate height from age 1 to age 12. | Increasing, Concave Down |

DUCKWEED | The results of an experiment in which Duckweed fronds - large compound leaves - were counted every week. | Increasing, Concave Up |

FLOWER | The height of sunflower plants as a function of time. | Increasing, Sigmoidal |

LUPINE | The growth of a Lupine from day 4 to day 21. | Increasing, Sigmoidal |

NSPLAICE | The weight of North Sea plaice as a function of time. | Increasing, Concave Up |

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

PLANT | The total area of the leaves of a plant as a function of time. | Increasing, Sigmoidal |

SOLE | The weight of North Sea sole as a function of time. | Increasing, Sigmoidal |

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 |

URUGUAY | In 1961 fertilized grass-legume pastures were introduced into Uruguay. This shows the total number of ranchers who adopted this new technology from 1965 to 1976. | Increasing, Sigmoidal |

YEAST | The amount of yeast as a function of time. | Increasing, Sigmoidal |
