### 6th Statistics and Probability - COMMON CORE - COMPLETE

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

statistics | a branch of applied mathematics concerned with collecting, organizing, and interpreting data. The data are represented by means of graphs; also the mathematical study of the likelihood and probability of events occurring based on known quantitative data o |

data | A collection of facts, such as numbers, words, measurements, observations or even just descriptions of things |

variability | refers to how spread out a group of data is. In other words, variability measures how much your scores differ from each other; also referred to as dispersion or spread. Data sets with similar values are said to have little variability, while data sets tha |

distribution | When data seems to be "gathered" around a particular value |

histogram | A graphical display where the data is grouped into ranges (such as "40 to 49", "50 to 59", etc), and then plotted as bars. Similar to a Bar Graph, but in this each bar is for a range of data. |

box plots | A method of visually displaying a distribution of data values by using the median, quartiles, and extremes of the data set. A box shows the middle 50% of the data.1 |

median | a measure of center in a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list—or the mean of the two central values, if the list contains an even number of values. Example: For the data |

mean | A measure of center in a set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list.4 Example: For the data set {1, 3, 6, 7, 10, 12, 14, 15, 22, 120}, the mean is 21. |

dot plot | A method of visually displaying a distribution of data values where each data value is shown as a dot or mark above a number line. Also known as a line plot. |

histogram | A graphical display where the data is grouped into ranges (such as "40 to 49", "50 to 59", etc), and then plotted as bars. Similar to a Bar Graph, but in this each bar is for a range of data. |

frequency tables | tables that show the number of occurrences of a particular item in a set of data |

cluster | When data seems to be "gathered" around a particular value. |

peak | the highest point in a graph |

gap | the ''large'' open space between some data points |

interquartile range | A measure of variation in a set of numerical data, the interquartile range is the distance between the first and third quartiles of the data set. Example: For the data set {1, 3, 6, 7, 10, 12, 14, 15, 22, 120}, the interquartile range is 15 – 6 = 9. See a |

measures of center | is a value that attempts to describe a set of data by identifying the central position of the data set |

measures of variability | measure of the spread of a data set. |

Mean Absolute Deviation (M.A.D.) | A measure of variation in a set of numerical data, computed by adding the distances between each data value and the mean, then dividing by the number of data values. Example: For the data set {2, 3, 6, 7, 10, 12, 14, 15, 22, 120}, the mean absolute deviat |

quartiles | The values that divide a list of numbers into quarters. |

lower quartile (1st quartile or Q1) | the median of the lower half of a set of data. |

symmetrical | when one shape becomes exactly like another if you flip, slide or turn it. |

skewed (skewness) | in statistics, a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. |

summary statistics | The information that gives a quick and simple description of the data. Can include mean, median, mode, minimum value, maximum value, range, standard deviation, etc. |

outlier | an element of a data set that distinctly stands out from the rest of the data. |
