HI;
Should a histograms classes be labled with class limits or class boundaries?
If I'm given the classes say 1-10 10-20 where does the 10 lie in the first or second class?
Hey anthonye.
When you have histograms the different regions must be disjoint: in other words if you have 1-20 with two bins then one bin might be [1,10) and the other is [10,20] so you don't have the same element in any two bins.
With regards to notation [ means you keep the value on the end point and ( means you don't include it so [1,2) keeps 1 but not 2 and [2,4] keeps both 2 and 4 and both keep anything in between these values.
