Op het eerste zicht lijkt het of er een schijnbaar verloop in de rode grafiek zit, maar dit is fout. Men kan dit puur aan het toeval toe wijten. Er zit geen patroon in, want wanneer we een muntstuk opgooien is dit puur aan het toeval te wijten als het resultaat kop of let is. De kans is 50%.
Er is dus ook logischerwijze geen seizoenaliteit aanwezig.

juiste conclusie

juiste conclusie, inderdaad geen seizoenaliteit aanwezig
