[Updated on 23.10.2011: I made a new better worksheet related to this topic. Click here. Tq]
Here we have 8 tables (i.e grouped data). I asked my students to draw histogram, frequency polygon and ogive for each table.
First there are 3 ways to draw histogram, by using
- lower and upper boundaries
- class intervals ... draw them all !
Second, there are 2 ways to draw frequency polygon, by using
- midpoints ... draw them all !
Third, there is only one way to draw ogive.
In other words, my students already drew 24 histograms, 16 frequency polygons and 8 ogives. They said "Teacher, you are cruel". I said "Yes, I am". (^_^)
