  • Method and apparatus for evaluating statistical significance over time
    Patent number: 8583695
    Abstract: Method and apparatus for evaluating statistical significance over time are described. A graphical display helps to establish if an improvement produces effective results over a period of time relative to similar results from a control group. This graphical display can be achieved in part by calculating and plotting the control group's “area of common performance” representing confidence intervals around the mean of the metric being analyzed. Subject group data can be represented by either a run chart or a box plot, depending on whether the subject group data is discrete or continuous. In some embodiments a hypothesis test can be performed on the data to verify the representation.
