Data Normal Spss. The KolmogorovSmirnov test uses the maximal absolute difference between these curves as its test statistic denoted by D In this chart the maximal absolute difference D is (048 041 =) 007 and it occurs at a reaction time of 960 milliseconds Keep in mind that D = 007 as we’ll encounter it in our SPSS output in a minute.
