Question | Answer |
---|---|

set | any collection of objects |

empty set | a set with no objects in it |

Venn diagram | a diagram that uses geometric shapes to show how sets are related |

meter (m) | a metric unit for measuring length equivalent to 100 centimeters |

centimeter (cm) | a metric unit for measuring length, equivalent to one hundredth of a meter |

millimeter (mm) | a standard metric unit for measuring length. 10 of these is equivalent to one centimeter, 1000 of them equal a meter |

benchmark | an item whose measure you know that can be used to estimate lengths. For example, you could use your height to estimate the height of a doorway |

gram | a standard metric unit for measuring mass (weight) |

milligram (mg) | a metric unit for measuring mass (weight) 1,000 of them equal one gram |

kilogram (kg) | a metric unit for measuring mass (weight) the equivalent of 1,000 grams |

metric ton | metric mass unit of mass equivalent to 1,000 kg |

sample | part of a whole set of objects being studied |

population | a whole set of objects being studied |

percent | “per hundred” or “out of 100” |

bar graph | a graph used to compare data by comparing the lengths of bars |

range | the difference between the greatest and the least values of a set of numerical data |

line plot | a plot displaying data above the appropriate points along a scale. The scale must include the greatest and least values of the data |

average | a single number used to describe what is typical of a set of data |

mean | the sum of a set of numerical data divided by the number of data items |

median | the middle data item in a set of data in numerical order. If there is no single middle item, the number halfway between the two data items closest to the middle |

mode | the data item or items that occur most often in a set of data |

front-end estimation | a method of estimation that focuses on the left-most digits, since they have the greatest value |

trading off | a method that involves taking away from one number and adding the same amount to another number, to have numbers that are easier to add using mental math |

stem-and-leaf plot | a display of data where each number is represented by a stem (the leftmost digits) and a leaf (the rightmost digits) |
