to future generations Investigate the impacts of human

activities on biological diversity Understand issues and decisions

associated with future activities.

Exploring Variation- pg. 8

All Domestic cats belong to one species,

Felis catus. However, these cats show many variation

Let’s take a look at some pictures of cats!

Two Types of Data

Discrete: A limited number of variations or categories; either/or. Example: Tall or short Bar Graph

Continuous: A range of variations or possibilities. Example: Height – 5’1”, 5’2”, 5’3”, 5’4”,

5’5”… Histogram

Three types of graphs!

Bar Graph: uses bars, shows a comparison between groups.

Three types of graphs!

Line Graph: joins points together to show progression or growth

Histograms

Continual data, summary graph

Showing a count of the data points falling in various ranges
