sytematically recorded information | |

the cases we actually examine in seeking to understand the much larger population | |

holds information about the same characteristic for many cases | |

this gives the possible values of the variable and the relative frequency of each value | |

this type of chart is also a food | |

when the conditional distribution of one variable is the same for each category | |

a region of the distribution where there are no values | |

the place in the distribution of a variable that you would point to if you wanted to attempt to summarize the distribution with a number | |

a distribution that is roughly flat is said to be | |

when each side of the center looks equal | |

extreme values that don't appear to belong with the rest of the data | |

middle value; half the data above, half below | |

difference between first and third quarters | |

square of the standard deviation | |

displays the five number summary as the central box with whiskers | |

when a point is more than 3.0 IQR from either end of the box in a box plot | |

value found by subtracting the mean and dividing by the standard deviation | |

tells how many standard deviations a value is from the mean | |

a useful family of models for unimodal, symmetric distributions | |
