a bar graph
I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
a height which on the set of data has the most numbers on so if it was height of people and there was 19 people with the same height and another height has 5 people in the group, and so that group has the most people in the group would be the one with the 19 people in.

The singers in a vocal group are divided according to their height.
It means that a government taxes a group of people without their representation in their government. The slogan "no taxation without representation" was coined when Britain taxed the American colonies but there was no American representation in British Parliament.
a concept
the french always said it
It depends. Normally, the average height in your group is the perfect height. Not too tall, not too short.
they are grouped by weight
No. A group is an idea and not an object. Even if it was an object, even objects can not be seen in their truest sense. You always only see a representation of an object. Take a keyboard. You are not seeing a keyboard. You are seeing a representation of the form of keyboardness.
