Pictograph | a graph using symbols to represent data |

Line Graph | a graph in which a line shows changes in data, often over time |

Pie Graph | a round graph that uses different sized wedges to show how proportions of of data compare with the whole set |

2 Ways Graphs Are Misleading | No lables or some are missing, scale does not start at zero |

Scatterplot | a graph showing paired data values |

Trend | a relationship between two sets of data that shows up as a pattern in a scatterplot |

Tally Marks | marks used to organize a large set of data |

Frequency Chart | a table listing each value that appeares in a data set followed by the number of times it appears |

Line Plot | a plot that shows the shape of a data set by stacking x's above each value on a number line |

Scale | the "ruler" that measures the heights of bars in a bar graph |

Interval | one of the equal sized divisions on a bar graph scale |

Horizontal Axis | the horizontal line on the graph |

Vertical Axis | the vertical line of the two lines on which the graph is built |

Range | the difference between the highest and lowest values in a data set |

Stem and Leaf Diagram | a graph showing the shape of a data set bt breaking each value into a "stem" part and a "leaf" part |

Median | the middle value in a data set when the values are listed from lowest to highest |

Mode | one of the values appearing most often in a data set |

Mean | the sum of the values in a data set divided by the number of values; the average |

Outlier | a number very different from the numbers in a data set |
