WebIf the data is normally distributed then the critical value Dn,α will be larger than Dn. From the Kolmogorov-Smirnov Table we see that. Dn,α = D1000,.05 = 1.36 / SQRT (1000) = 0.043007. Since Dn = 0.0117 < 0.043007 = Dn,α, we conclude that the data is a good fit for the normal distribution. Example 2: Using the KS test, determine whether the ...
