### Fractions, Decimals, Percents, and Using Data

Term | Definition |
---|---|

bar graph | a graph with horizontal or vertical bars that represent data |

denominator | the "downstairs" number in a fraction that describes the number of equal parts in the whole |

numerator | the "upstairs" number in a fraction that describes the number of parts of the whole being considered |

equivalent fractions | fractions with different denominators that name the same amount |

improper fraction | a fraction with a numerator that is greater than or equal to its denominator |

mixed number | a number that is written using both a whole number and a fraction |

circle or pie graph | a graph in which a circle and its interior are divided into sectors corresponding to parts of a set of data |

percent | per hundred; out of a hundred |

percent circle | a tool that is used to measure and draw figures that involve percents, such as circle graphs |

fraction stick | a diagram used to represent simple fractions |

rounding, round to the nearest... | to approximate a number to make it easier to work with or to check for precision |

repeating decimal | a decimal in which one digit or a group of digits is repeated without end |

sector | a region bounded by, and including, an arc and two radii or a circle; also called a wedge |

unit fraction | a fraction whose numerator is 1 |

unit whole | an entire object, collection of objects, or quantity being considered in a problem |

common denominator | a nonzero number that is a multiple of the denominators of two omr more fractions |

contour map | a map that uses contour lines to indicate areas having a particular feature, such as elevation or climate |

contour line | a curve on a map through places where a measurement is the same |

line plot | a sketch of data in which checkmarks, Xs, or other symbols above a labeled line show the frequency of each value |

cubit | an ancient unit of length, measured from the point of the elbow to the end of the middle finger |

fair game | an equal chance of winning or losing |

fathom | a unit of length equal to 6 feet, or 2 yards |

frequency table | a table in which data are tallied and organized |

frequency graph | a graph showing how often each value occurs in a data set |

great span | the distance from the tip of the thumb to the tip of the little finger, when the hand is stretched as far as possible |

landmark of data | a notable feature of a data set; landmarks include the median, mode, mean, maximum, minimum, and range |

maximum | the largest amount; the greatest number in a set of data |

minimum | the smallest amount; the smallest number in a set of data |

median | the middle value in a set of data when the data are listed in order from smallest to largest or vice versa. If there is an even number of data points, the median is the mean of the two middle values |

mode | the value or values that occur most often in a set of data |

range | the difference between the maximum and the minimum in a set of data |

stem-and-leaf plot | a display of data values in which digits with larger place values are "stems" and digits with smaller place values are "leaves" |

normal span | the distance from the end of the thumb to the end of the index finger of an outstretched hand |

quick common denominator (QCD) | the product of the denominators of two or more fractions |

simplest form of a fraction | a fraction that cannot be renamed in simpler form (reduced) |

sample | a part of a population intended to represent the whole population |

survey | a study that collects data |

unlike denominators | denominators that are different |
