Example: Height of Orange Trees
You measure the height of every tree in the orchard in centimeters (cm)
The heights vary from 100 cm to 340 cm
You decide to put the results into groups of 50 cm:
• The 100 to just below 150 cm range,
• The 150 to just below 200 cm range,
• etc...
So a tree that is 260 cm tall is added to the "250-300" range.
