### [Worksheet] Chapter 6 - Statistics (Mathematics Form 4) Histogram, Frequency Polygon & Ogive

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
• midpoints
• class intervals ... draw them all !
Second, there are 2 ways to draw frequency polygon, by using
• histogram
• 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". (^_^)

Tq for your visit. Sbnrnye klu dh diberi skala lebih senang, just terus lukis je histogram. Klu x bagi yg pening tu ... :)

Amir Fahmi Jaafar

Hello, actually if you know that particular class is a modal class then you should already know the frequency :)

wildness

that means the modal class is equal to frequency ,right,teacher

Amir Fahmi Jaafar

The modal class is depend on the frequency. The modal class is a class with the highest frequency. :)
