Statistik einfach erklärt: Zentrale Tendenz, Streuungsmaße, Häufigkeit und Kreisdiagramme
Zentrale Tendenz und statistische Grundlagen
Diese Seite bietet einen umfassenden Überblick über grundlegende Konzepte der Zentrale Tendenz Statistik und verwandte statistische Methoden. Sie erklärt verschiedene Maße der zentralen Tendenz wie Zentralwert (Median), Modalwert und Mittelwert sowie deren Berechnung anhand von Beispielen. Zusätzlich werden wichtige Streuungsmaße wie Spannweite und Boxplot vorgestellt, die zur Beschreibung der Datenverteilung dienen. Die Seite behandelt auch die Berechnung von absoluten und relativen Häufigkeiten sowie die Erstellung verschiedener Diagrammtypen zur visuellen Darstellung statistischer Daten.
Definition: Die Statistik ist jenes Teilgebiet der Mathematik, das uns bestimmte Methoden lehrt, Daten auszuwerten und graphisch darzustellen.
Vocabulary: Der Zentralwert, auch Median genannt, ist der Wert, der genau in der Mitte einer geordneten Datenreihe liegt.
Example: Bei der Berechnung des Zentralwerts für eine ungerade Anzahl von Werten (z.B. 2,2,3,4,4,5,5,6,6) wird der mittlere Wert gewählt. Bei einer geraden Anzahl wird der Mittelwert der beiden mittleren Zahlen berechnet.
Highlight: Die relative Häufigkeit berechnet sich aus der absoluten Häufigkeit geteilt durch die Gesamtanzahl der Versuche. Sie kann in Prozent ausgedrückt werden und ist wichtig für die Wahrscheinlichkeitsrechnung.
Example: Beim Erstellen eines Kreisdiagramms wird der Winkel für jeden Sektor berechnet, indem man den Prozentwert mit 3,6 multipliziert. Ein vollständiger Kreis hat 360°, daher entspricht 1% einem Winkel von 3,6°.
Die Seite bietet praktische Anleitungen zur Berechnung und Interpretation verschiedener statistischer Kennzahlen. Sie erklärt, wie man einen Boxplot erstellt, absolute und relative Häufigkeiten berechnet und verschiedene Diagrammtypen wie Kreis- und Balkendiagramme zeichnet. Diese Informationen sind besonders nützlich für Schüler und Studenten, die die Grundlagen der Statistik erlernen und anwenden möchten.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
