 Für das Unterscheiden von Hering und Lodde hast du bereits die Längen (in cm) aller 100 Fische gemessen und damit das untenstehende Histogramm erstellt.
   - Wenn du mit der Maus über das Histogramm fährst, so wird der Threshold als rote Linie eingeblendet. Alles links vom Threshold wird vom Apparat als Lodde klassifiziert, alles rechts vom Thresold als Hering. Die rote Zahl über dem Threshold gibt an, wie viele Fische falsch klassifiziert werden (wie viele Fische in einem falschen Korb landen). Welches ist der kleinste Fehler, den du erreichen kannst? Trage das Resultat ins Textfeld ein. {{gem/match?0=N4IgTgpg5hAeAOIBcIB6BtABAXQFQAYs8ASEAGhADMAbAQygGdkQBLckAFzg+ZAF8gA#0a73bc9400492abf}}
-  - Natürlich ist das zu schön um wahr zu sein. Schaue das Histogramm noch einmal genau an. Da stimmt doch etwas nicht! Halte deine Vermutung im Textfeld fest. {{gem/plain?0=N4XyA#41416c56366ce4e9}}

Halte deine Vermutung im Textfeld fest.\\ 💡 Tipp: Das Histogramm zeigt die Längen der Fische. Lodde gibt es grosse und kleine. Wie sieht es bei den Heringen aus? {{gem/plain?0=N4XyA#41416c56366ce4e9}}
