Box plot graph

Salve ho questa serie di dati (sono voti in matematica riportati da 19 alunni:

3  3  4  4  5  6  6  6  7  7  7  8  8  9  9  10  10

Il box plot generato indica:

Q1=4,75

Q2=Me=6,50

Q3=8,25

Mentre i valori dovrebbero essere

Q1=5

Q2=Me=7

Q3=8

Come mai non calcola i valori corretti?

Re: Box plot graph

Hi,

Box plot can be configured to show different values for the Outliers/Wiskers/Box, standard setting is Tukey.

The different configuration options are described in the help;

With Your example data this is what I get;
