A is a graph based upon medians. It shows the minimum value, the lower median, the median, the upper median, and the maximum value of a data set. It is also known as a box-and-whisker plot.box plot |

five-number summary |
The numbers needed to construct a box-and-whisker plot are called the . The five-number summary are: the minimum value, , the median, , and the maximum value.five-number summary |

Extremes |
The extremes are the maximum and minimum values in a data set. |

five point summary |
The numbers needed to construct a box-and-whisker plot are called the five-point-summary. The five points are the minimum, the lower median (Q1), the median, the upper median (Q3), and the maximum. |

line of fit |
A line of fit is a straight or continuously curved line representing the trend of changes in the comparison of two data sets (or one set of bivariate data). |

Median |
The median of a data set is the middle value of an organized data set. |

observed data |
Observed data are the values that result from computations performed on the input variable. |

Outlier |
In statistics, an outlier is a data value that is far from other data values. |

Quartile |
A quartile is each of four equal groups that a data set can be divided into. |

skewed |
As with the horizontal skewing of a histogram, stem plots with a obvious skew toward one end or the other tend to indicate an increased number of outliers either lesser than or greater than the mode. |

statistical correlation |
Statistical correlation is a representation of possible related changes in values between the two sets of data. |

trends |
Trends in data sets or samples are indicators found by reviewing the data from a general or overall standpoint |

uniform |
A uniform shaped histogram indicates data that is very consistent; the frequency of each class is very similar to that of the others. |
