Na het verwijderen van de uitschieters zien we dat de boxplot werd aangepast, maar dat er andere observaties buiten de snorharen vallen en dus als uitschieters beschouwd worden.

goede oplossing en goede interpretatie, 
 
Reproduce the previous computation 
 
Change the R code by imposing restrictions on the data. For instance, we might insert the 
following line of code at the appropriate position: 
z <- z[z[,1]*z[,2]>800000 & z[,1]*z[,2]<1700000,] 
 
you can observe the entire R code in the blogged computation (below) 
Result: 
 
If we select only those screens for which the number of pixels (=width * height) is in the interval ] 
800000, 1700000[ then most of the outliers are removed. In both computations the boxes (= middle 
50% of observations are not strongly affected.
