Chicken (game) respectively. The line in graph on the left shows the optimum probability of playing the escalated strategy for player Y as a function of "x". The line in the second graph shows the optimum probability of playing the escalated strategy for player X as a function of "y" (the axes have not been rotated, so the dependent variable is plotted on the abscissa, and the independent variable is plotted on the ordinate). The Nash equilibria are where the players' correspondences agree, i.e., cross. These are shown with points in the right hand graph. The best response mappings agree (i.e., cross)
Paired data medicine. In this case the data is "paired" as it is likely the blood pressure "after" giving the medicine will be related to the blood pressure of that patient "before" the medicine was given. The statistical tests used to compare sets of data have been designed for data that is either paired or unpaired and it is important to use the correct test to prevent erroneous results. Examples of tests for unpaired data: Examples of tests suitable for paired data: Paired data Scientific experiments often consist of comparing two or more sets of data. This data is described as unpaired
